In this paper we report on the geochemistry, Sr Nd isotope compositions, and zircon U Pb dating of Late Triassic basalts from the Nieru Formation (T3n) in the Kampa region, southern Tibet. The basalts have relatively low contents of MgO, TiO2, and total alkalis (K2O + Na2O), and they have affinities to tholeiitic basalt. They exhibit weakly fractionated rare earth element (REE) patterns with slight depletions in LREEs and slightly negative Eu anomalies on a chondrite-normalized diagram. On a primitive-mantle-normalized spider diagram, they are characterized by slight enrichments in large ion lithophile elements (LILEs) and relatively flat patterns of high field strength elements (HFSEs), except for depletions in Ba, Nb, Ta, and Ti. Their initial 87Sr/86Sr ratios vary from 0.718133 to 0.738977 and eNd(t) values are relatively depleted (4.09–5.22), similar to mid-ocean ridge basalts in the Yarlung Zangbo ophiolite. We propose the T3n basalts were derived from a shallow and depleted mantle source by relatively high-degree partial melting in the spinel stability field. They underwent slight crustal contamination as well as the fractional crystallization of clinopyroxene. The T3n basalts are similar to typical back-arc basin basalts (BABB) such as the Okinawa BABB. This indicates an extensional back-arc-basin setting along the northern margin of Gondwana during the Late Triassic. The initial opening of the Neo-Tethyan Ocean was related to the southwards subduction of the Paleo-Tethyan oceanic plate and back-arc-basin spreading during the Late Triassic. Magmatic activity along the passive continental margin records key information on continental break-up and incipient ocean development.

They are commonly found along some fault systems, such as the Three Pagodas fault zone of western Thailand. The changing characteristics of many hot springs during the 26 December 2004 Sumatra Earthquake include both temperature and chemical compositions indicate the value to study them in connection with the regional tectonics. However, in this paper the focus is on investigation of hot spring sites for development of tourist/local industry as it has been done in many locations in Thailand. The results of geophysical and geotechnical investigations, jointly conducted by the AIT and Mahidol University research teams, in Kanchanaburi province of western Thailand are presented.

Complex infilling-dominated deposits of the sheeted-vein or stockwork type are less abundant (10% of primary deposits). Other types arc replacement-dominated deposits (24%). tin-tantalum mineralized pegmatites (12%) and breccia deposits (1%). Placer tin deposits derived from the primary tin mineralization in the pre-Miocene basement are the major source of tin. The oldest terrestrial sediments deposited on the extensively pcneplaned basement have a Miocene-Pliocene to Lower Pleistocene age. These sediments, which arc up to 60 m thick, host the most important placers. They are overlain by younger alluvial strata or marine sediments, which are up to 25 m thick and usually do not contain minable tin mineralization. Fluvial allochthonous bottom placers are of major economic importance. Fluvial residual bottom placers, fluvial above-bottom placers and alluvial-fan placers are also significant. Eluvial, colluvial and littoral placers arc of minor importance.

The Kwae Noi River is running along the TPF in the south whereas the Kwae Yai River is running along the SSF in the north. The southeastern continuation of both faults is obscured by thick Cenozoic sediments. Hence, surface lineaments cannot be traced with confidence. However, based on some interpretations of the airborne magnetic survey data, the trace of such faults are designated to run through the western part of Bangkok and the northern end of the Gulf of Thailand. Paleo-earthquakes and the presence of hot springs along the fault zones indicate that they are tectonically active. The changes of both physical and chemical properties of the water from Hin Dart Hot Spring and those of the surface water from a shallow well at Ban Khao Lao during the Great Sumatra-Andaman Earthquake on 26 th of December 2004 clearly indicated that the southeastern continuation of the TPF is at least as far south as Pak Tho District, Ratburi. Our new evidence of the alignment of the high heat flow in the upper part of the Gulf of Thailand verified that the TPF also extend into the Gulf via Samut Songkhram Province. Studies of the seismic data from two survey lines along the Western part of the upper Gulf of Thailand acquired by Britoil Plc. in 1986, namely Line A which is approximately 60 km long, starting from Bang Khen passing through Bang Khae and ending in Samut Songkhram and Line B is approximately 30 km long starting from Samut Sakon ending in Samut Song Khram suggest that all the faults or fractures along these seismic profiles are covered by sediments of approximately 230 m thick which explain that the fault underneath these seismic lines is quite old and may not be active. The absent of sign or trace of the TPF Path to the west suggested that there is no segment of such fault along these seismic lines.

Sediments of these deposits are characterized by clasts of various rock types especially the resistant ones with frequent big tree trunks, logs and wood fragments in different sizes and various stages of transformation from moldering stage to lignification and petrification. Widespread pyritization of the lower horizon suggests strongly reducing environment during burial. The Tha Chang deposits have been received much attention from geoscientists especially paleontologist communities, as they contain fragments of some distinct vertebrate species such as Stegadon sp., hominoid primate, rhinoceros Aceratherium and others. Based on the associated mammal fauna and hominoid fossils, the late Miocene ( 9 - 6 Ma) was given...

It consists of several segments with northwest-southeast orientation. One segment (N35W) of the Si Sawat Fault in the area of Ban Thung Makok, Danchang, Suphanburi western Thailand was examined using a combined geological and geophysical surveys. The result of the trenching suggests an evident of a normal fault with 85 cm offset cutting through a series of the Quaternary colluvium sediments of which the minimum age of 9,151 ± 1,830 years B.P. Key words: active fault, Si Sawat Fault, Kanchanaburi, Western Thailand 1.

With two exceptions, in sites near the western edge of this region, all fragments are layered (muong-Nong-type) tektites. It appears that large layered tektites are mainly found by rice farmers in fields that were forested until the recent past. The presence of layered tektites in this 40×130 km area implies that impact melt that fell in these areas was not enough to flow if it was deposited on a sloping surface. The absence of splash-form tektites from the region indicates that the layer was still molten when masses having shapes (teardrops, dumbbells, etc.) produced by spinning reached the ground. To account for this and to allow time for the melt to flow a few tens of centimeters requires that the atmosphere remained hot (>2300 K) for a few minutes. Tektites that are in place are almost always associated with a wide-spread 10-cm to meter-thick layer of laterite. In two cases (one involving layered, one involving splash-form tektites), where accurate stratigraphic control demonstrated that the tektites were still in section, they were sited on top of the laterite layer just below a layer of aeolian sand.

The following radiolarians (13 species belonging to seven genera) were identified and systematically investigated: namely Albaillella sp., Ceratoikiscum sp., Stigmosphaerostylus variospina, Stigmosphaerostylus cfr. vulgaris, Stigmosphaerostylus cfr. delvolei, Stigmosphaerostylus sp., Stigmosphaerostylus? sp. A, Stigmosphae-rostylus? sp. B, Stigmosphaerostylus? sp. C, Trilonche? sp., Spongentactnia exilispina, Pylentonema antiqia, and Archocyrtium sp. These radiolarians indicate the Tournaisian–Visean, Mississippian (early Carboniferous) in age. The present authors have already reported a Tournaisian radiolarian fauna which is slightly older than the present fauna from black bedded chert in the Saba YoiKabang area. This is an additional r...

We found chert breccia layers in northern Nong Prue area, mainly consisting of angular to sub-angular chert clasts with matrices of silt-sized chert grains and clay minerals. We discriminated uppermost Pennsylvanian–Lopingian (upper Carboniferous–upper Permian) and Middle Triassic radiolarian-bearing chert clasts from four different levels of the chert breccia; 28 species of 15 genera with one radiolarian gen. et sp. indet. are identified. On the basis of sedimentary characteristics of the chert breccia, we suggest that the chert breccia is of sedimentary origin. The radiolarian assemblages reported here, together with previously known lithological and paleontological evidence, further indicate that the chert breccia was deposited ...
