Understanding porosity and density

For most rocks porosity varies from less than 1 to 40 The porosity of a rock depends on many factors including the rock type and how the grains of a rock are arranged For example crystalline rock such as granite has a very low porosity <1 since the only pore spaces are the tiny long thin cracks between the individual mineral grains
