About Science Frontiers

Science Frontiers is the bimonthly newsletter providing digests of reports that describe scientific anomalies; that is, those observations and facts that challenge prevailing scientific paradigms. Over 2000 Science Frontiers digests have been published since 1976.

These 2,000+ digests represent only the tip of the proverbial iceberg. The Sourcebook Project, which publishes Science Frontiers, also publishes the Catalog of Anomalies, which delves far more deeply into anomalistics and now extends to sixteen volumes, and covers dozens of disciplines.

Over 14,000 volumes of science journals, including all issues of Nature and Science have been examined for reports on anomalies. In this context, the newsletter Science Frontiers is the appetizer and the Catalog of Anomalies is the main course.


Subscriptions to the Science Frontiers newsletter are no longer available.

Compilations of back issues can be found in Science Frontiers: The Book, and original and more detailed reports in the The Sourcebook Project series of books.

... -o -where is that crater? 770,000 years ago, a huge meteor hit somewhere on earth and strewed an immense batch of tektites and microtektites over fully 10% of our planet's surface (about 5 x 107 square kilometers). This is called the "Australasian strewn field." Such a recent cataclysm must have left a large and inescapable crater somewhere. The problem is that no one has yet found it. (Ref. 1) Many lines of evidence suggest that the missing crater is in Indochina. C.C . Schnetzler and J.F . McHone located four likely structures in Laos from Landsat images. However, visits to these areas found no evidence of an impact. (Ref. 2) So, this mystery persists. How were the Muong Nong tektites formed? Muong Nong tektites are unusually large (up to 24 kilograms), layered tektites. They are found in an area 1,000 kilometers in extent from Hainan Island to southern Indochina. Their large sizes imply that they are probably close to the missing crater mentioned above. Still unresolved is whether they were originally puddles of molten rock near the elusive crater or local ejecta analogous to volcanic bombs. (Ref. 1) Is the "age paradox" finally resolved? Some Australian geologists have stratigraphically dated the Australasian tektites as being just a few thousand rather than 770,000 years old. (SF#8 ) The 770,000-year figure is derived from the presence of Australasian microtekites at the Brunhes-Matuyama magnetic reversal and is, therefore, a " ...

Science Frontiers ONLINE No. 78: Nov-Dec 1991 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Heavy bombardment of southeast asia 700,000 years ago Tektites are found all over much of Australasia -- an immense area. The tiny, often-illustrated teardrop- and button-shaped tektites clearly seem to have been formed when an extraterrestrial object smashed into the earth, melted terrestrial rock and soil, and splashed the fluid droplets over thousands of kilometers of Australia and Southeast Asia. Solidifying in flight, these par-ticles fell by the millions. Aerodynamically sculpted Australasian tektite But another type of tektite is also found in Southeast Asia. These are the layered or Muong-Nong tektites, which are not aerodynamically sculptured. They come instead in large, irregular masses, 3-20 centimeters thick, weighing up to 24 kilograms. Their layered appearance is thought to result from flow and stirrings as they solidified in small pools of melted rock and soil splashed from nearby impact craters. These irregular chunks of solidified melt could not have traveled great distances like their streamlined brothers. They lie at most only a few crater diameters from their parent craters. Since layered tektites are found over an area 800 x 1140 kilometers in extent, and they are not far-travelers, Southeast Asia must have been peppered with many small cosmic projectiles 700,000 years ago (the disputed age of the event). Whereas geologists have been searching diligently for a single huge crater (perhaps 100 kilometers in diameter) to explain the Australasia strewn field, ...
