Consider first where the carbon in the earth's crust resides: Petroleum 201 x 1018 grams Coal 15 Limestone 64200 Biosphere 0.3 In this article, these figures are made more understandable by physical descriptions of some of the truly colossal deposits of oil, coal, and limestone. For example, in the Canadian Rockies, the Livingstone limestone was deposited 2000 feet deep on the margin of the Cordilleran geosyncline but thins eastward to about 1000 feet in the Front ranges. ". .. it may be calculated to represent at least 10,000 cubic miles of broken crinoid plates." Two implications are: Even if the earth's biosphere were completely converted into oil, coal, and limestone each year, the earth would have to be far older than the 6000 years desired by the creationists, unless most of the carbon deposits had non-biological origins, which seems unlikely. The immense inventory of carbon tied up in biologically produced deposits was originally abiogenic. Where did it come from? Abiogenic methane and carbon dioxide released from the crust seem the most likely sources. This means that the crust must have once had, and may still have, prodigious supplies of methane. T.

However, the itinerary of northern Alaska cannot even be guessed at. Present thinking is that this portion of the state was close to the geographic north pole during the late Cretaceous. But this is the period when the huge coal deposits were formed on the Arctic slope. Much of this coal comes from evergreens, which could not have survived in high latitudes due to the lack of sunlight. So, the pieces of the puzzle are at hand, but their travels are a mystery.

When an archeologist finds the contents of ancient garbage dumps (" middens") fused into a glassy slag. he has to ponder a bit longer. First, a bit of background. Natural glasses can be created in several ways. Impact-heating by meteorites or asteroids probably fused the famous slabs of Libyan Desert Glass and also the Darwin glass found in Australia. More curious are the peculiar glassy clinkers of fused wood ash found in hollow snags in trees after intense forest fires. This is called "combustion metamorphism." Combustion metamorphism is also common where undergound coal seams have caught fire and burn for decades. Humans get into the act, too. The ancient Scots piled up trees around their rock forts and fused the stones together with fire. (Why they bothered is unknown.) However, a different sort of natural glass has been found in east-central Botswana. There, archeologists have found 5-inch-thick layers of glassy slag interleaved with ashy soil in ancient middens (garbage dumps). These middens are not associated with pottery kilns or iron smelting. It is hard to imagine what could have melted layers of garbage, including pottery, plant material, and other biomass. Analysis of the slag indicates that temperatures of 1155-1290 C were required to fuse the garbage. Open fires could not have attained the necessary temperature ...

If you wish, you can accelerate the substance's demise by touching a match to it; it is packed with potential energy. The substance is methane hydrate, and it is found in prodigious quantities in oceanic sediments. Each cubic centimeter of methane hydrate contains about 160 cubic centimeters of methane at standard conditions; it is a concentrated source of natural gas. In fact, methane hydrate deposits in the world's oceans hold twice as much carbon as all the coal, oil, and gas reserves on land! But methane hydrate may be much more than a future fuel source; it may have been humanity's savior in eons gone by; it may be our future nemesis. You see, methane hydrate is very unstable; changes of temperature or pressure on a global basis can trigger the release of immense volumes of this greenhouse gas from oceanic deposits. For example, when the Ice Ages lowered ocean levels by locking up water in the advancing ice caps, pressures on ocean-bottom methane hydrate lessened and, according to some speculators, released enough gas so that the increased greenhouse heating turned back the Ice Ages. (Was Gaia at work here?) On the other hand, if present human activities are truly stoking the greenhouse effect, ...

... quantities of methane and higher hydrocarbons locked up in frozen hydrates around the edges of the continents. Actually, the small methane burps are minor problems compared to the catastrophic climate changes that could be forced if just a small portion of the gases frozen under the sea floor were released into the atmosphere. Gas-hydrates are unimpressive when brought to the surface -- just dirty, fizzy ice. However, taken together, they contain more carbon than all the world's oil fields, perhaps much more. Most estimates fall between 1,700 and 11,000 billion tons, but there is one scientist who pegs these cold-storage carbon deposits at 4,100,000 billion tons. In comparison, human releases of carbon to the atmosphere via the burning of wood, gas, coal, and even the collective flatulence of all the planet's animals are trivial. Geological evidence confirms that past climate swings were associated with large injections of carbon into the atmosphere and oceans. A major contributor to these "carbon burps" may be decomposing methane hydrate. Until recently, climatologists have questioned the sizes of gas-hydrate deposits, but cores extracted from the Blake Ridge off the Carolina coast confirm the immense amounts of gases precariously locked up in sea-floor sediments. The stratum of gas hydrates in the Blake Ridge alone covers 26,000 square kilometers -- enough gas is there to supply the U.S . for 107 years.

Olbers (of Olbers Paradox fame) remarked that meteorites are extremely rare in the fossil record. While meteorites are found in profusion in some specially favored surface deposits (Antarctica and Australia's Nullarbor Plain), there are very few records of any being found in the immense volumes of coal, gold ores, and other geological materials that have been mined down the centuries. Of course, many meteorites escaped the notice of miners who were looking for something else. Nevertheless, few have been reported from strata more than a few thousand years old. (See ESI8 in Neglected Geo logical Anomalies.) It is therefore surprising that a veritable lode of fossil meteorites has been found in a limestone quarry at Kinnekulle, in southern Sweden. "During the sawing of a few thousand cubic meters of Ordovician limestone into 2-3 cm thick slices, 25 fossil meteorites have been found. All meteorites, except, four, have been found in a 60 cm thick bed called the Archaeologist. This bed represents a few hundred thousand years and contains several hard ground surfaces...Many of the Archaeologist meteorites are prominently angular in shape whereas others are round. This seems difficult to reconcile with an atmospheric breakup of a single large meteorite." B. Schmitz and M. Tassinari, the authors of this paper, suggest that this rare concentration of fossil meteorites ...

JUN 2000 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects From Nature's Atelier One of geology's more fascinating mysteries concerns the formation of concretions. Concretions are structures within rock that differ in form and/or composition from the matrix. Often, they form around an impurity of some sort, say, a tiny fossil. If concretions were all nicely spherical or crystalline in shape, we might be able to explain them as we do with the oyster's pearl and winter's snow-flake. Unfortunately for the theorists, concretions usually come in bizarre shapes -- shapes an avant garde sculptor might appreciate. Not only do concretions come in weird geometries but they may be replicated in prodigious numbers, like the famous Kimmeridge "coal money." Additionally, some flint concretions are arrayed in thick chalk beds in amazingly regular three-dimensional arrays that tax the ingenuity of any theorist. To illustrate the extremes of nature's inorganic-chemical imagination, we now provide some illustrations from a recent two-part article in Rocks & Minerals and one of our catalog volumes.

More trees may be good for the environment in the tropics, but the reverse is true in lands that are covered with snow most of the year. This is be-cause snow reflects much of the impinging solar energy back into space. If these northern lands were heavily forested, much of the solar energy would be absorbed and converted into heat. Climate-modellers confirm that sunlight-reflecting snow is better for the environment than trees. (Anonymous; "Reflect on It," New Scientist, p. 19, May 13, 2000.) Hydroelectric power is clean . Although widely proclaimed to be among the cleanest energy sources available, some hydroelectric powerplants actually con-tribute more greenhouse gases than large coal-fired plants! Submerged vegetation is the problem. When it decays, it releases greenhouse gases---in quantity. The forests first submerged by the reservoirs behind the dams contribute gases for only a few years. Most of the troublesome biomass is fed into the reservoirs from upstream. Compounding the problem are the vast areas of stagnant water behind many hydroelectric dams. There, in the absence of dissolved oxygen, the rotting vegetation generates methane, which is a much more potent greenhouse gas than CO2.

Indeed, all of the reference books confidently label charts with firm dates for the appearance of fishes, the demise of the dinosaurs, and so on. Alas, things are not quite as certain as they appear. Radiometric dating is not all that precise; errors may be large indeed. Take the Pennsylvanian period for example. It is part of the Carboniferous period, when many of the great coal deposits were laid down. The classical duration of the Pennsylvanian -- used in many texts -- is 34 million years. A meticulous new study of central European stratigraphy now pegs the Pennsylvanian as spanning only 19 million years. Now that's a 44% change! This new figure for the duration of the Pennsylvanian has already cast doubt on the origin of the famous Pennsylvanian cyclothems (repetitive strata) in North America. It had been thought that these seemingly cyclic deposits were correlated with sea level changes forced by variations in the earth's orbit (the Milankovitch periods). With this substantial compression of Pennsylvan-ian time, this correlation falls apart. The cyclothems, which are of impressive area and thickness, now seem to have been created by some other, still unrecognized phenomenon. (Klein, George deV.; "Pennsylvanian Time Scales ...

First, if they are made up of small chunks of matter, the laws of celestial mechanics dictate that they should quickly spread out radially into much wider rings in just a decade or two. In other words, if the rings are ancient they should not have maintained their present form. Second, the rings are invisible when one would expect them to be bright like Saturn's . Yet, they reflect less light than the blackest coal dust. T.C . Van Flandern proposes that each ring is actually a single satellite, so small that we cannot see it, and that it sheds gases as it orbits. This small solid body would make the celestial mechanics people happy, and the gases would be invisible to the eye but still absorb light, making the ring of gases detectable when Uranus occults a star. (Van Flandern, Thomas C.; "Rings of Uranus: Invisible and Impossible?" Science, 204:1076, 1979.) Comment. An alternative explanation is that the rings are recently acquired and will soon disappear.
