摘　　要：在北京西南周口店地区,由于房山岩体的侵入使得围岩发生了不同程度的热接触变质作用。而岩浆侵入过程中的热能在传导时逐渐递减,使得同一沉积岩单元中也会形成不同的变质相带。本文以周口店地区一条龙下马岭组红柱石片岩为例,通过分析小范围内红柱石结晶程度的差异,探究该地区房山岩体侵入热接触变质作用对红柱石结晶程度的影响。In the zhoukoudian district of southwest Beijing, due to the intrusion of the rock mass in fangshan, the surrounding rock has had different degrees of thermal contact metamorphism. In the process of magma intrusion, the heat energy gradually decreases in conduction, so that different metamorphic phase zones can be formed in the same sedimentary rock unit. This paper dragon horse hill in zhoukoudian area group of andalusite schist, for example, through the analysis of small differences in degree of crystallization of andalusite, within the scope to explore the region well thermal contact metamorphism rock intrusion of andalusite crystallization degree of influence.
