Abstract. Understanding the behavior of global climate system during extremely warm periods is one major themes paleoclimatology. Proxy data demonstrate that equator-to-pole temperature gradient was much lower mid-Cretaceous "supergreenhouse" period than at present, implying larger meridional heat transport by atmospheric and/or oceanic circulation. However, reconstructions circulation Cretaceous have been hampered a lack appropriate datasets based on reliable proxies. Desert distribution...
Recent paleoseismic investigations have identified a number of active faults in Northern and Western Thailand. Thailand is an intraplate basin range province, comprised north-south-trending Cenozoic intermontane grabens half grabens, bounded by north- to northwest-striking normal normal-oblique northeast-striking left-lateral strike-slip faults. The basin-bounding are marked steep, linear fronts with triangular facets wineglass canyons slip rates 0.1 0.8 mm/yr. Based on limited data, the...
The crater and proximal effects of the largest known young meteorite impact on Earth have eluded discovery for nearly a century. We present 4 lines evidence that 0.79-Ma Australasian tektites lies buried beneath lavas long-lived, 910-km 3 volcanic field in Southern Laos: 1) Tektite geochemistry implies presence young, weathered basalts at site time impact. 2) Geologic mapping 40 Ar- 39 Ar dates confirm both pre- postimpact basaltic exist proposed wholly cover it. 3) A gravity anomaly there...
Abstract Seismic hazards in Thailand and adjacent areas were analyzed mainly on the basis of geological fault data. We identified 55 active zones using remote-sensing data earthquake source parameters derived from both catalogues. selected strong ground-motion attenuation models by comparing application several candidate with recorded Thailand. Both deterministic (DSHA) probabilistic (PSHA) approaches used—DSHA for design critical construction PSHA non-critical construction. also applied two...
Abstract The 2004 Indian Ocean tsunami deposited a sheet of sand with surficial bedforms at the Andaman coast Thailand. Here we show recognition and key internal sedimentary structures as criteria supercritical flow condition. presence well‐preserved capping implied dominant inflow. Sets including parallel lamination, seaward landward inclined‐laminations, downstream dipping laminae indicated antidune that were generated by current in depositional stage during A set cross‐laminations...
The cooling of spaces in tropical regions, such as Southeast Asia, consumes a lot energy. Additionally, rapid population and economic growth are resulting an increasing demand for space cooling. ground-source heat pump has been proven reliable, cost-effective, safe, environmentally-friendly alternative heating various countries. In countries, the presumption that may not provide better thermal performance than normal air-source arises because difference between ground atmospheric...
The devastating December 26, 2004, tsunami produced abundant geologic effects along the Andaman coast of Thailand. inundated numerous sandy beaches and flowed over adjacent aeolian dunes. On some dunes, scoured circular holes 10–30 cm in diameter, its waning phases, it coated with mud. locally deposited a sand sheet that ranged from 0–30 thickness, an average thickness approximately 10 cm. Sedimentary structures within include ripples inflow outflow, graded bedding, parallel lamination,...
Abstract The c. 500-km-long Mae Ping fault zone trends NW–SE across Thailand into eastern Myanmar and has probably undergone in excess of 150 km sinistral motion during the Cenozoic.

Abstract It has previously been proposed that the Sibumasu block of Southeast Asia, which contains glaciomarine deposits, became detached from Gondwana margin during Early Permian. A combination facies analysis and identification dropstones dump structures a Lower Permian diamictite‐bearing sequence at Phuket, Thailand, adjacent islands suggests sediments originated as debris‐flow deposits. The in study area corresponds to Ko Sire He Formations, both consist three principal lithofacies:...
