铬铁矿成矿理论的探索已有数十年的历史,对其成矿作用、控制因素及分布规律的认识正在逐步深入。铬铁矿是基性、超基性岩中岩浆分异的产物。研究岩浆物质在运动过程中的分异,对探讨铬矿的形成及分布具有重要意义。岩浆岩流动构造是常见的一种现象,它可以大致追朔岩浆侵入时的运动状态。本文拟讨论超基性岩中的原生流动构造,进而研究其与成矿作用的关系及找矿意义。一、流动构造的形成和特征 Chromite metallogenic theory exploration has decades of history, understanding of its mineralization, controlling factors and distribution is gradually deepening. Chromite is a product of magmatic differentiation in basic and ultrabasic rocks. Studying the differentiation of magmatic materials during the movement is of great significance for the study of the formation and distribution of chromite. Magmatic flow structure is a common phenomenon, which can be roughly traced magmatic intrusion state of motion. In this paper, the authors discuss the primary flow structure in ultrabasic rocks, and then study their relationship with mineralization and prospecting significance. First, the formation and characteristics of the flow structure
