摘    要:含煤沉积岩系中,陆源碎屑沉积岩占绝大多数。“杂基”或“基质”是否参加或如何参加陆源碎屑沉积岩的分类与命名,是沉积岩工作者十分关心,经常讨论的问题。部分学者主张杂基在陆源碎屑沉积岩中影响分类与命名,部分学者有不同的论述。本文根据笔者在西北地区几个煤田沉积岩工作中的资料,以青海木里侏罗纪煤田河流环境含煤沉积岩系中,杂基混入特征为例,试谈一孔之见,不妥之处请批评指正。

ON THE NOMENCLATURE OF MATRIX IN THE TERRIGENOUS CLASTIC SEDIMENTARY ROCK
Institution:Laboratory of Qinghai Coal Geologic Exploration Corporation
Abstract:The terrigenous clastic sedimentary rock is absolute majority in the coaly sedimentary series, its grain-size texture is mixed.with various degrees of matrixes. When the sediments transtorm from the transportation of high-energy environment into lower-energy environment, the carriers of higigh-energy make soil and sand deposit, so that the clastic sedments within grainsize of matrix ( 0.03mm≈5φ)-may easily mix up with coarser grain texrture, In this paper, the author uses the examples of the features of fluvial environment from Qinghai Muli coal field, to explain the close relations between the matrix mixed and medium energy and micro-facies environmet control. It is suggested that using thematrixes the nomenclature of the terrigenous clastic sedimentary rock, does not effect on classification but only on nomenclature, The rock with 10-20% matrix is named x x x rock of matrix, The rock with 25-50% matrix is uamed matrix quality x x x x rock. In the basic nomenclature of tarrigenous clastic sedimentary rock, the terms matrixand matrix qualityare used to describe the difference of the mixed amout-and the degrees of matrix, so that they may be easily applied in worke. In addition, the author proposes a preliminary view of the differences between matrixes and cements for the terrigenous clastic sedimentarg rockrefromed by virtue of temperature, pressure and structure,.
