试论构造相构造相系和构造相序列

ON TECTONIC FACIES, TECTONIC FACIES SERIES AND TECTONIC FACIES SEQUENCE

构造相、构造相系和构造相序列三位一体概念的提出,是试图将由构造动力引发的物质的结构调整和组成调整在空间、时间和演化上有机地结合起来。从此,确立了地壳物质的结构调整的形迹和组份调整的踪迹的各种相标志,和在统一应力场或同一构造事件产生的构造相之间的空间组合和联系的构造相系,以及反映同一地区不同构造相系空间叠加、时间演化的构造相序列。以期获得地壳物质在构造事件中运动规律的最大信息量。

The systematic concept concerning the tectonic facies, tectonic facies series and tectonid facies sequence is an idea which attempts to combine closely the regularities of structural and composittional adjustments of the crustal material under tectonic dynamics in terms of space, time and evolution. So, some indicators of facies are determined here according to the features of structural adjustment and the traces of composional adjustment of the crustal material. The next step is to define the tectonic facies series, which refers to the spatial combination and relationship of the tectonic facies caused by a unifo rmstress field and the same tectonic event. Then the tectonic facies sepunce is defined, which reflects, in terms of time and evolution, the regularity of superimposing and interfering of defferent tectonic facies series nseries in the same area.
