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。
