Supracrustal sequences free of early strong deformation The early deformation of Jingangku formation complex of Hengshan Wutai group complex has formed a bedding parallel S〓 gneissic and schistosity, occasionally bedding parallel recumbent folds in layers. The early deformation of the near-horizontal ductile shearing isn't very strong in Wutai group complex. The orientation of shear movement is NNW—SSE.

经受早期强烈变形的表壳岩系岩系恒山五台岩群金岗库岩组和五台山五台岩群最早期的变形是平行地层层理的S1片麻理和片理，偶见层内的顺层掩卧褶皱，这些早期近水平韧性剪切变形在五台岩群大都不甚强烈，对地层层序的扰动也很弱，剪切运动方向是北西西——南南东向的。

As for sulfur isotopic composition, the general feature of two types deposits is a single peak distribution. All δ〓s values of the ores are near zero. The difference of different deposits lies in that the δ〓s values (1. 8-5. 2‰) of LDT are of small positive value and are similar to that of the metamorphic rocks and dioritic porphyrites in the region while the δ〓s values of SDT are always near zero. Features above suggest that two types of deposits have closely genetic relationship to metamorphic and magmatic rocks.

硫同位素组成上，两类金矿床共同的特征是均具有明显的单峰塔式效应，且δ〓S值均位于0值附近不大的变化范围内；不同的是，近程式金矿的δ〓S平均值均接近于0，与该类金矿具密切成因联系的岩体的δ〓S值也接近于0值，而远程式金矿的δ〓S平均值均为小的正值，变化范围为1.8～5.2‰，区内太古代变质岩及矿区内闪长玢岩脉的全岩δ〓S值位于这一区间内，反映了远程式金矿床其成矿物质不仅来源于重熔岩浆，同时还可能部分来源于变质岩围岩。

Heat flows derived from garnet, chromite/chromium-spinel and pyroxene of xenoliths, xenocrysts in Mengyin and Fuxian kimberlites are higher than 40mW/m〓 calculated from the pyroxene inclusions in diamonds, and the range of pressure is 20～40kb (equivalent to 65～130km). Metasomatism (as indicated by yimengite and lindsleyite in Mengyin) is very strong in this depth range. Lherzolite, wehrlite, and diamond-free high-Ca harzburigite around the world are derived from this depth also. The observation suggests that the low-Ca harzburigitic environment for diamond stability had been changed significantly when the kimberlitic magmas erupted. This resulted from fluid interaction with harzburigite. The geotherm of the Cenozoic lithospheric mantle beneath Eastern-North China platform is higher than oceanic one. The temperature from the interior of the Tan-Lu faults is higher than that from apart off the fault.

除金刚石中的辉石温压投点落于40m W/m〓占地温线上外，捕虏体及捕虏晶中石榴石，铬尖晶石及单斜辉石的投点均偏离该地温线，显示较高的地温特点，而且捕虏体及捕虏晶的压力范围多在20-40kb(相当于65-130km)间，该深度范围内地幔的交代作用特别发育，如蒙阴大量发育的沂蒙矿、钛钾铬石等就发育于该深度范围，世界范围内不含金刚石的高钙方辉橄榄岩、二辉橄榄岩、异剥橄榄岩也分布于该区中，一方面表明捕虏体的主要取样位置已不在金刚石稳定区中，另一方面也表明金刚石稳定的橄榄岩环境，在金伯利岩侵位并捕虏他们时已发现了明显的改造，这种改造作用主要是通过长期的熔流体与先存的橄榄岩相互作用的结果。
