Further to our current research in layered and splashed tektites , and numerous impact multiple craters in Ubon; our 1997 new discovery evidences in Khorat, both in northeast Thailand, includes the wide continental burns, mass extinction oftrees, ancient elephants, other mammals; and the thick catastrophic loess. All of these were linked to an extraordinary global disaster in a catastrophic event in Thailand and East Asia. These evidences were belonged to and superimposed on the known… 

Potential of impact-structure hydrocarbon plays in continental Southeast Asia

The pre-Tertiary of continental SE Asia, the Indosinia and Sundaland tectonic blocks, most probably hosts a number of brecciated impact structures with good reservoir properties. Hydrocarbons that

Australasian impact crater buried under the Bolaven volcanic field, Southern Laos

Significance A field of black glassy blobs, strewn across about 20% of Earth’s Eastern Hemisphere, resulted from the impact of a large meteorite about 790,000 y ago. The large crater from which these



Field recovery of layered tektites in northeast Thailand: Evidence of a large-scale melt sheet

We recovered Australasian tektites in place throughout a 40×130 km region in north-east Thailand extending from the Laotian border westward to a line connecting Na Pho Klang in the northeast through

In search of the Australasian tektite source crater: The Tonle Sap hypothesis

— The source crater for Australasian tektites remains to be positively identified We suggest that Tonle Sap, a roughly oval lake in south-central Cambodia, may represent the remnant of that crater.

At Site 612 (Leg 95), a 20-cm-thick layer containing microtektitic glass spherules separates middle Eocene from upper Eocene siliceous nannofossil oozes. These microtektites presumably are part of

Excavation and analysis of layered tektites from northeast Thailand: Results of 1994 field expedition

— We have analyzed the size, shape, composition, and spatial distribution of 6 kg of layered tektite fragments excavated from a 3 m × 3 m area near the town of Ban Huai Sai in northeast Thailand. Our

Timing Between a Large Impact and a Geomagnetic Reversal and the Depth of NRM Acquisition in Deep-Sea Sediments

The hypothesis that large meteorite impacts on earth may trigger geomagnetic reversals is partly based on the close stratigraphic occurrence of the Australasian microtektite layer to the

North American microtektites in Deep Sea Drilling Project cores from the Caribbean Sea and Gulf of Mexico

Several thousand microtektites (125 to 1,000 µ m in diameter) have been found in cores from two Deep Sea Drilling Project sites: site 94 in the Gulf of Mexico and site 149 in the Caribbean Sea. The
