Abstract

The lower Cretaceous hydrothermal sedimentary rocks had been found in Baiyinchagan sag of Inner Mongolia Erlian basin in recent years. The hydrothermal sedimentary rocks were rich in special minerals including clay sized albite, ankerite, natrolite, franquanite, barite, etc., and were only developed in semi-deep to deep lacustrine facies. The hydrothermal sedimentary rock can also be characterized by its log response with extremely high GR(GR=700~1 100 API), which is 2~4 times that of natural gamma value of normal argillaceous, and remarkably fluctuation in resistivity logging from as high as 2 000 Ω·m to 0.2 Ω·m. By the petrologic characteristics of the hydrothermal sedimentary rocks,the detailed analysis of single well core,combined with the corresponding logging response features, four hydrothermal actives can be recognized in Tenggeer-Douhongmu formation in the study area. One hydrothermal process will form a low natural gamma value lithologic section-the peak shape high natural gamma value cyclic deposition. A complete hydrothermal process consists of three stages: ①Early overflow process which precipitate low GR dolomitic or zeolitic fine grain rock with dolomite and zeolite laminae, zebra or interface layer. And ②Jet flow process with increasingly active hydrotherm. The laminae or interface layer of dolomite and zeolite will be deformed or even disrupted and result in dolomitic fine grain rock and clastic rock consisting of dolomitic or zeolitic intraclasts. After the energy of hydrotherm exhausted the hydrothermal activity will return back. ③Sluggish overflow stage and results in argillaceous dolomite rock and partial dolomitic mudstone with extremely high GR response.
