混杂堆积

混杂堆积（Mélange）②不是孤立的地质现象，它是一种在特定地质历史时期、特定地质条件下的特殊地质体。

M é lange is not an isolated geological phenomenon but a kind of specific geological body formed under particular geological conditions in a certain period .

万宝沟岩群是东昆仑造山带一套构造&沉积混杂堆积地层，由外来系统和基质系统两部分组成。

The Wanbaogou Group-complex is made of exotic blocks and matrix strata of a tectonic-sedimentary m é lange .

笔者讨论了其术语、岩块、基质特征、形成机制和古地理古构造条件，并列表分析了它与混杂堆积的区别。

The relevant terminology , block and matrix characteristics , genetic mechanism , palaeogeography and tectonics are discussed in this paper together with their distinction from melanges .

另一方面，在隧道及地下工程施工过程中开挖的岩石，作为固体废弃物混杂堆积，不仅占用宝贵的土地资源，而且也给生态环境造成一定程度的破坏。

At the same time , the excavated rock in tunnel and underground engineering , as solid offal , not only occupy valuable land but also pollute environment to some extent .

在甘肃武都县城北第四纪地层剖面中，马兰黄土之下发育有一套以大量碎屑和部分粘土组成的混杂堆积体。

In the profile of quaternary stratum , near Northern Wudu county seat , Gansu province , there was a set of diamicton , covering by the loess , containing a lot of clastic fragment and partly clay .

根据造山带的地层和构造特点，以构造地层学的观点将造山带地层分为三类：（1）构造混杂型，是由混杂岩组成的混杂堆积，构造作用强烈，原始地层层序无法恢复；

Based on tectonic and stratigraphic feature , strata in orogenic belts can be divided into three types : ( 1 ) tectonic melange-type strata composed of tectonic m é lange whose original stratigraphic sequences can hardly be reconstructed because of tectonic deformation ;
