The fieldwork and some testing work study on the mineralogical,petrolgical and geochemical characteristies and the short-ware infrared spectroscopy of the K,Na-bearing rocks, ore-bearing rock series as well as tourmalin indicate that:(1) The content of B2O3 in the ore-bearing strata correlated positively with its thickness.
本文以前寒武纪地体辽宁后仙峪硼矿床(西石洞沟矿段)的含硼岩系为研究对象,通过野外地质观察和部分测试,对含矿岩系中的变粒岩、浅粒岩的矿物学、岩石学、地球化学及短波红外光谱特征进行研究,初步得出以下结论:(1)含矿层中B_2O_3的富集程度与含矿层的厚度变化呈正相关关系;而矿体中B2O3富集程度与矿体厚度变化相关性不明显。

The ore-bearing porphyries of the Gangdese porphyry copper belt in the southern Tibet plateau possess the essential characteristics of adakite and formed from partial melting of subducted Tethyan oceanic crusts under eclogite facies conditions.
本文用冲江和拉抗俄两个矿区含矿斑岩的黑云母和斜长石斑晶测定了它们的~(40)Ar/~(39)Ar年龄,结果表明两个矿区虽然相隔百余千米,但形成时间非常一致。
补充资料：含煤岩系
| 含煤岩系 coal-bearing strata 一套含有煤层或煤线的沉积岩系。又称煤系、含煤沉积或含煤建造。构成含煤岩系的沉积岩大都呈灰、灰绿、灰黑和黑色，主要是各种粒度的砂岩以及粉砂岩、泥岩、灰质泥岩和煤组成，砾岩、粘土岩和石灰岩也常见，有时也见到铝质岩、油页岩、硅质岩和火山碎屑岩等。含煤岩系一般富含动、植物化石。有时还可见到多种碳酸盐结核、硫铁矿结核以及硅质结核等。含煤岩系的形成时代从古生代（主要是晚古生代）至第三纪。含煤岩系在世界各大洲的许多地方都有发现。含煤岩系的变化，主要受控于它形成时的古构造和古地理环境。不同时代、不同地区的含煤岩系，其特征不同。含煤岩系的厚度由几米至几十米甚至上万米，含煤层数由一至一二百层不等，煤层厚度相差也极大，有的厚度超过100米。 |
