All stages of the Carboniferous are represented in northeast Thailand and their exposures are delimited in this paper.In northeast Thailand, Carboniferous rocks are widely exposed in an area where Loei and Wang Saphung are the main towns, an area 20–40 km wide and 140 km long. In parts of this area, they are overlain by Permian strata (mainly limestone) in the core of a syncline. Middle-Upper Devonian limestone, shale and chert occur occasionally in the central and northern parts of the area. They are less widely distributed than the Carboniferous rocks but are obvious features because the limestone forms karstic hills and the chert outcrops are prominent.An important development of shale during the Middle-Upper Carboniferous has favoured differential erosion so that today these rocks are distributed commonly in flat areas with paddy fields; the shale concealed under a few meters of earth.

Obliquity of subduction beneath Sumatra induces large strike-slip faults in Sumatra and its margin, whereas the subduction is almost perpendicular to the trench southwest of Java. The nature of the transition between these two subduction regimes is of major interest. New data collected with the Indonesian R.V. Baruna Jaya III, show that the Cimandiri Fault Zone of west Java continues out to sea. Sinistral activity seen on land, can be the conjugate of dextral strike-slip faulting along a NW-SE prolongation of the Sumatra strike-slip fault in the forearc domain. A structural transition is occurring south of the Pelabuhan Ratu Gulf and may therefore correspond to a change in the subduction regime. To the west, oblique subduction induces partitioning of the motion into convergent motion and northwestward strike-slip motion. To the east, opposite Java, subduction is normal and typical forearc basin develops. In the transition area, the curvature of the margin induces a northwestward increase of the obliquity of subduction and consequently of the lateral component of the partitioned motion. North-westward, displacement of the forearc domain results in internal extensional deformation and ablation of accreted sediments south of the Sunda Strait, explaining the concave shape of the deformation front.</div>","PeriodicalId":85022,"journal":{"name":"Journal of Southeast Asian earth sciences","volume":"12 1","pages":"Pages 85-93"},"PeriodicalIF":0.0,"publicationDate":"1995-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/0743-9547(95)00023-2","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72123168","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
