在详细的矿床地质、岩石地球化学和同位素年代学综合研究基础上，结合区域构造演化的特点，着重对金矿与煌斑岩的成因关系进行了剖析，认为戈枕含金剪切带煌斑岩与金矿不仅具有生成构造环境上的联系，而且对金成矿具有重要的物源贡献，是金矿找矿标志。

These dilatation veins are the ultramafic—mafic intrusive sheets in early stage, which occurred the strong boudinages and the shearing rotation forming θ、Φ、δtype porphyroclasts generally, as the series different size deformation zones; the features of the leucocratic felsic veins in middle stage; the pink granitoid veins in later stage, show a gneisses evolution process from the deep tectonic facies to the middle tectonic facies.

这些扩张脉体，早期阶段为超镁铁质—镁铁质侵入岩席，受后期构造改造岩席发生强烈石香肠化或受剪切发生旋转，呈θ、Φ、δ碎斑系，总体构成一系列规模不等的变形带；中期阶段以发育淡色长英质脉体为特征；晚期阶段为肉红色花岗质脉体，反映出片麻岩由深构造相向中浅构造相变化的过程。

Mylonitic coal may develop in the center of strongly deformational belt in pressing tectonic stress field. Since mylonitic coal is limited in a narrow area, biggish area in that tectonic coals of brittle deformation distribute is favorable for CBM exploration. Moat of areas are advantageous for formation of coalbed fractures and increase of permeability in extension stress field, but it is easy to beget dissipation of CBM and decrease of gas content. Therefore, study of structure of gas reservoir should be taken seriously.

研究表明，挤压应力场作用下，在强变形带的中心及其附近，可以形成糜棱煤类构造煤，但糜棱煤分布较为局限；在较大范围内形成脆性变形系列的构造煤，是煤层气勘采的有利区带；拉张构造应力场中，大部分区域内有利于煤层裂隙的形成和渗透率的提高，但易造成煤层气的散失，含气量降低，应重视有利的储气构造的研究。
