Comparison of continental Mesozoic rock in northeastern Thailand and connecting area in Laos (Thai)

Abstract

The continental Mesozoic rocks between northeastern Thailand and connecting area in Laos were
studied and compared with the geological exploration of Thai, Vietnamese and Chinese geologists both on the
surface and underground by drilling. The results of the study indicate that the stratigraphies of the rock can be
compared, although there are some differences of opinion about rock arrangement because the data and the 
measurements have small differences. Normally, the continental sediments are more limited in extension than
marine sediments but the stratigraphies of rocks can be compared clearly. The data that identifies bed rock are
the evaporite layers of 3 beds of rock salt and 1 bed of potash rock on the lower salt bed whereas the other
bed rocks mostly are sandstone, siltstone and claystone intercalating together. However, the study is significant
because of the exchange of ideas between international geologists. In the future international cooperation can
develop the knowledge because these stratigraphies contain a lot of geological resources, both dinosaur-bone
fossils and rock salt and potash minerals, that can be developed for the benefit of all ASEAN people.
