金伯利岩中铬尖晶石的矿物共生、性质和成份 铬尖晶石是金伯利岩中含量较低的矿物,但它稳定地出现在金伯利岩中,并且由于它的一些特点而有着重要作用。金伯利岩和玄武岩的许多二辉橄榄岩捕掳体中铬尖晶石的存在,正是在较大的压力和温度范围内进行能够导致上地幔含尖晶石橄榄岩中间压力相析出的实验研究的基础。同时,铬尖晶石也是金伯利岩含矿(含金刚石)性的重要标志之一,并在直接
The mineral symbiosis, properties and composition of chromium spinel in kimberlite Chromium spinel is a low content mineral in kimberlite, but it is stable in kimberlite and plays an important role due to some of its characteristics. The existence of chrome spinel in many lherzolite captives from the kimberlite and basalts is an experimental study that is capable of precipitating the intermediate pressure phase of the upper mantle containing spinel peridotites over a wide range of pressures and temperatures Foundation. At the same time, chrome spinel is also one of the important symbols of kimberlite ore-bearing (including diamond)
