Abundant Dinosaur Track at the Site Tha Uthen, Northeastern Thailand

E-mail Print PDF

Abstract

Late Triassic to Early Cretaceous terrigenous sedimentary rocks are widely distributed in northeastern Thailand. These sedimentary rocks, traditionally referred to as the Khorat Group, contain abundant dinosaur bones and footprints. In this study, we investigated dinosaur footprints at the site Tha Uthen (Huai Dam Chum), where is located at the eastern edge of northeastern Thailand. Abundant footprints were found in this site where dinosaur footprints have been first reported by Loeu.ff et ol. (2003). It has been reported by ichnologists that track makers of these footprints are estimated to small-sized theropoda, ornithopoda and crocodylomorpha until now. This footprint site is protected and managed by the government of Thailand. The purpose of this study is to measure dinosaur footprints in detail, and perform the quantitative community analysis based on measurement data.

A note on Foliated contact Metamorphic Rocks in Western Shan-Thai

E-mail Print PDF

Abstract

Not until recently at least three separated locations of originally thought to be older regional metamorphic rocks of Thailand have been extensively mapped and petrographically investigated in details by undergraduate students of the Geoscience Program, Mahidol University at Saiyok, Kanchanaburi province. These areas belong to the Western Shan-Thai, which from north to south, includes Uthong area, west of Suphan Buri; Tha Muang-Tha Maka area, east of Kanchanaburi and Pran Buri area, north of Prachuab Khiri Khan. Based on lithologic resemblances and grades of metamorphism, the rocks in these areas had been assigned range of ages from Inferred Precambrian, Cambrian-Ordovician and Ordovician. Careful characterization of rock associations, revealed nonexistence of paragneiss and migmatite in these areas, contradictory to those that usually occur in the true high grade regional metamorphic rocks of the inferred Precambrian age exposed elsewhere. Traceable to the outside lower grade regionally metamorphosed meta-argillaceous limestone and meta-argillite in two of the studied areas, the equilibrated higher grade calc-silicate hornfels and micaceous schistose hornfels inside the contact aureole signified by the presence of orthopyroxene among others, suggests the characteristic minerals of the contact metamorphism. More foliated contact metamorphic rocks which might have been misleaded mapped as Inferred Precambrian age such as in Lin Thin area and Khao Chong In see area, in Kanchanaburi and Khanom area, in Nakhorn Sri Thammarat are to be unraveled. The common occurrences of high temperature/low pressure regime in the inferred Precambrian high grade regional metamorphic rocks of western Shan-Thai terrane as earlier published indicates the Buchan or Abukuma type facies series.

Thailand Sustainable Development Mechanism of Geopark

E-mail Print PDF

Abstract

The commence in 2001 and 2004 of geoconservation activity of the Deportment of Mineral Resources (DMR) was the compilation of the previous geological data accumulated over a century and produced 2 publications regarding geoheritages and geotourism sites respectively in order to disseminate to public. The actual geoconservation projects have been initiated since 2010 in Satun province and continually running until  this fiscal  year mostly in  southern, northeastern and other ports of Thailand. All projects have the objectives to conserve geoheritages and conservatively developed them as sustainable and proper highest exploitation especially in academic, tourism and socio-economic purposes which  is the  key concept of geopark. The projects are implemented under 5 processes, geosites assessment, collaboration to establish geopark, geopark and geological knowledge dissemination, study and research and development. These processes will be implemented to seek for the first global geopark in Thailand. Up until now DMR has developed geoconservation site evaluation criteria, guidelines to establish geopark and 217 geoconservation sites, mainly in south and northeast Thailand, has been defined including 2 potential areas for geopark  development in Satun and Ubon Ratchathani Province with their own management and development policy, plan and measures.

Abstract

I. Step of minerals investment and regulatory management

Law on Minerals (Amended Version) No.02/NA, dated 20 December 2011 to be composed 11 parts and 102 Article. The aim is to defines the principles, regulations and measures  regarding the management, protection, utilization of minerals and mineral  resources, and the inspection of minerals activities, with the aim of ensuring that prospecting, exploration, mining and processing of minerals are highly efficient in conjunction with environmental protection and are consistent with the National Socio-­Economic Development Plan in order to create conditions for gradual economic growth, industrialization, progressive modernization, sustainable mineral development and to improve the standard of living of all ethnic groups.

An Enterprise or a Company may undertake mineral prospecting in one block and the block area shall not exceed three hundred square kilometers and an extension of the area not permitted. Subsequently an area granted for mineral exploration shall be based on the results of the mineral prospecting work already undertaken.

Global GEOPARKS

E-mail Print PDF

Abstract

The Earth is a dynamic planet with a remarkable geological history and diversity. The continental masses and oceans on the surface of the Earth have changed continuously and evolved over much of geological time.

Plate tectonic activities resulted in several earthquakes and volcanic activities which resulted in large-scale crustal deformation and changed in ocean and continents. With the different time interval the abiotic process operated continuously in macro and micro scale for more than four billion years. Mountain ranges have formed and been eroded, and the rock debris deposited and recycled.
