然而热河生物群产出的古地理环境和盆地沉积特征的研究由于受到后期构造破坏和风化作用的影响，难以开展详细的野外工作，研究程度较低。

At the same time, the plane distribution of diagenetic facies is concluded, and then pore evolepment of different microfacies is contrasted.

其次，在沉积相、微相研究的基础上，结合大量薄片及地化等资料，进行了成岩作用、成岩阶段、成岩环境及成岩序列的研究，确定了成岩相的平面展布，最后探讨了不同微相的孔隙演化过程。

Trace element record is formed by the coupling action of early diagenetic perturbation and human pollution, and usually showes the covariance with iron or manganese record.

沉积物微量元素记录是早期成岩改造和人为活动污染综合作用的结果，往往与Fe或Mn的记录呈相关波动。

It is nothing else than impurities prenatally inherent in ore that seriously affect the quality of the latter, which is formed as a result of geological vicissitudes including diastrophic movement, eruption of volcano, sedimentation, glaciation and weathering etc., under the action of which pyrogenic rocks, volcanic complex, aqueous rocks, sedimentary rocks etc., come into being, some of which exist in a stage of symbiosis, the main cause of the absence of pure rocks in nature, wherein lies the reason for the need of separation technology and apparatus, namely, ore-dressing devices and equipment, so far impotent to meet the requirements of metallurgical industry the scientists make every endeavor to elevate to a new high by laser separation.

没有什么比矿石形成之前就存在的杂质对矿石品质的影响更为重大。矿石是火成岩、火山群、水成岩、沉积岩等成形时，在包括地壳运动、火山爆发、沉积、冰蚀、风化等地质变化的作用下而形成的。而有些地质变化在一个发展阶段中存在共生现象。自然界无杂质岩石缺乏的主要原因在于需要分离技术和设备来完成，即：需要选矿设备和装置。而迄今为止，这些设备还难以适应冶金业的需要，虽然科学家们尽一切努力用激光分离技术将冶金业提高到一个新的高度。
