| 中文摘要:本文简单回顾了构造相的研究概况，分析了构造相的控制因素；笔者从岩石的能干性出发，提出了地层能干性的新概念，计算了燕山地区前中生代各地层的能干性和印支期变形的温压条件，并对燕山地区印支期构造相进行了系统的划发，建立了印支期的相结构。提出了本区印支期构造相以变流相为主的观点。 |

| Abstract:This paper simply reviews the study of tectonic facies and its controlling factors. Based on the study of the rock strength, the author put forward a new concept of layer strength,calculate the layer strength of pre_Mesozoic strata and the temperature and pressure of the Indosinian deformation in the Yanshan area, systimatically divide the Indosinian tectonic facies and set up the texture of the Indosinian tectonic facies in the Yanshan area. It is suggested that flexural flow facies is the main tectonic facies in the Yanshan area during the Indosinian movement. |
