Analysis of the Distribution and Microscopic Characteristics and Disintegration Characteristics of Carbonaceous Rocks: A Case Study of the Middle Devonian Luofu Formation in Western Guangxi of China

Table 1

Main pore types of carbonaceous rocks.

Pore type	Features	Form
Organic pore	The pore size of organic matter is generally micron level, and some can reach nanometer level	Round, oval, long strip and irregular shape, etc.
Intergranular pore	The aperture is nanometer and micron level	Triangle, strip, and irregular shape
Intergranular corrosion pore		Round, oval, long, triangular, and irregular
Intragranular pore		Elliptical, irregular, etc.
Intragranular dissolution pore		Round, oval, irregular, etc.
Microfracture	The width is generally nanometer, and the length is generally micron level	Strip shape
