... ago. The sudden change in the abundance of forest plants suggests that the winters became much more severe while the summers remained about the same. At about the same time, the radiolaria were devastated by some sort of disaster. This was also the time when the North American tektite strewn field was deposited -- a field that stretches halfway around the world. John O'Keefe hypothesizes that some of the tektites and microtektites that rained down during this period missed the earth and went into orbit around it, forming an opaque Saturn ... like ring. This ring might have lasted a million years or more; and its shadow could have caused the extrasevere winters postulated from botanical data. (O 'Keefe, John A.; "The Terminal Eocene Event; Formation of a Ring System around the Earth," Nature, 285:309, 1980.) Comment. Many who have previously speculated about terrestrial ring systems, such as I.N . Vail, were called pseudoscientists! Reference. The North American tektites are the subject of Section ESM3 in our ...

Science Frontiers ONLINE No. 87: May-Jun 1993 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Giant impact-wave deposit along u.s . east coast Along the shore from North Carolina to Maryland and also into Chesapeake Bay, deep-sea drillers have charted the Exmore Boulder Bed. No minor deposit this; it is is over 60 meters thick in places and covers more than 15,000 square kilometers. In the bed are found boulders (up to 2 ... in diameter), cobbles, pebbles, and traces of tektite glass and shocked quartz. The youngest microfossils date from the Eocene, and argon dating of the ejecta yield a date of 35.5 million years, which correlates with the North American tektite strewn field. C.W . Poag et al interpret this boulder bed as follows: "On the basis of its unusual characteristics and its stratigraphic equivalence to a layer of impact ejecta at Deep Sea Drilling Project (DSDP) Site 612 (New Jersey continental slope), ... postulate that this boulder bed was formed by a powerful bolidegenerated wave train that scoured the ancient inner shelf and coastal plain of southeastern Virginia. The most promising candidate for the bolide impact site (identified on seismic reflection profiles) is 40 km north-northwest of DSDP Site 612 on the New Jersey outer continental shelf." (Poag, C. Wylie, et al; "Deep Sea Drilling Project Site 612 Bolide Event: New Evidence of a Late Eocene Impact-Wave Deposit and a Possible Impact Site, U.S ...
