The Mineral-bearing Potential In Se' Ertengshan Group, Inner Mongolia

This thesis studies the Sertengshan group in northern margin of north China platform. Through file observation, engineering geological exploration , sample selection, the author performs microelements study for the samples and reviews the geological data of deposition magnetite in research area. This thesis focus on the geological features, chemical features of geochemistry, ore forming model, formation factor ore bearing and controlling factor of formation of mineral deposit. The following achievements have reached:1.Sertengshangroup are fault block outcrops in Sanpiangou, Liuxigou, Shilongwan, Liangwugou and Wusuogou.Sanpiangou strike northeast, Liuxigou strike southeast and a litter in east of Block. Sertengshan group distribution in gneissic plagioclase granite of Late Archean and gneissic granite.2. Ag,As,Sb,Au,Cu,Mo,Pb,Zn have formed geochemistry anomaly and have been noticeable concentration center and regular shape.3. Magnetite ore output with layered,lens-shaped .ore seam and top roof have clear limitted.4. Sertengshan group is important ore potential rock Series of Anshan-type magnetite in the middle of Inner-Mongolia.sedimentary and metamorphic magnetite have produced in Sertengshan group such as Sanheming deposits,Gongyiming deposits,Dongwufenzi depositsit.the large area of Sertengshan group will be have potential to find Anshan-type magnetite doposits.5. To analysis microelements of have found doposits in Sertengshan group has yielded that the Primary Rock Formation are intermediate basic volcanic andtuff-silicalite-carbonatite-clastic rock to construct. The iron ore has formed in the interval of volcano eruptionan and the layer are large .Not to thick to show frequent volcanic activity .The iron ore build formed in the tranquil stage .
