| 摘 要： | 柏树岗金红石矿床含矿岩石主要为下元古界宽坪组角闪片岩等,矿体呈（似）层状,产状与地层一致。矿石可划分为角闪石型片状（或块状）、绿帘石型片状（或块状）、斜长石型块状、云母（或绿帘石）石英型片状、绿帘黑云斜长石型片状、白云母型片状、黑云母型片状（或块状）及石英脉型块状等类型。金红石早于、同时或晚于主变质期脉石矿物形成,以前两种为主,其杂质含量不超过5％,主要为FeO、Cr2O3及SiO2等;决定金红石杂质含量的因素主要为杂质元素离子半径,次为杂质元素在矿石中含量。矿床是下元古界富钛火山-沉积岩系经泥盆纪的区域变质作用形成的。

| Abstract: | The ore-bearing rocks of the Baishugang rutile deposit are represented mainly by the amphbole schist and the other things of the Early Proterozoic Kuanping group, which form orebodies as sub-bedded and occur in a direction consistent with that of the deposit strata. The ore types have been defined such types as sheet (or massive) epidote, massive plagioclase, sheet mica (or epidote)-quartz, sheep epidote-plagioclase-quartz, sheep muscovite, sheet (or massive) biotite and massve quartz vain. The rutile formed at the time earlier than, or later than, or , occasionally, the same term as, the metamorphic gangue minerals did. It contains 5% at most of impurity which, consisting mainly of FeO, Cr2O3, and SiO2, all depend in quantities upon their ionic radii and contents in ores. The deposit resulted from the regional metamorphism of the Early Proterozoic titanium-rich volcanosedimentary rocks in the Devonian period. |
