Does anyone know anything about these so-called impact structures? HC potential of meteorite impact structures, focus on Sundaland
http://www.mail-archive.com/[email protected]/msg03653.html This talk states: "Several impact structures have been recently discovered in pre-Tertiary Peninsular Malaysia. In the Langkawi islands three of four arcuate ridges are associated with cleaved quartz that crops out as a sill and dyke complex. Other shock-metamorphic features include ribbon quartz and mosaicism. The two major craters, named Mahsuri Rings, partially overlap and each is about 2.4 km across. In 280o - 100o direction their centres are 600 metres apart." and "Another proven impact structure is the Paloh Ring that straddles the state boundary between Terengganu and Pahang. The proof consists of planar deformation features (PDFs) and mosaicism in vein quartz intruded into undivided Carboniferous metasedimentary strata that compose the lower eastern slope of the 623m high Paloh peak." Does anyone know anything about these alleged impact craters?
