We reconstruct the ground surface temperature history by analysis of temperature-depth (T−z) profiles from two deep boreholes some 200 km apart in Panxi, southwest China. Consistent results have been derived using a variety of analysis methods: individual inversion of each T−z log, simultaneous inversion of the derived transient components of the two T−z logs, inversion of the average of the transients, and inversion of the residual T−z data after the steady state has been removed. Results show that a warming of about 1°C from 1600 to 1900 AD is evident in the borehole temperatures. The results also indicate that such a warming is at least in part a recovery of the climate from a preceding cold episode.

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}
