Density ScienceDirect
网页2015年1月1日 In igneous rocks, density increases from felsic (acid) to mafic (basic) types. Each rock type shows a range of density values. 1 In comparison with most sedimentary rocks, this range is relatively small and is mainly result of a variation of the particular rock composition and a very small influence of pore or fracture volume. The density of

Density and Porosity (Chapter 2) Fundamentals of Rock
网页2021年11月19日 Two definitions of rock density are bulk density and solid matrix or skeleton density. Density depends on porosity, which is classified into open and closed porosity. Types of pores are defined by their interconnectivity, connectivity with surface, and geometry. Due to pore volume decrease with depth, sedimentary rocks possess three
