CHAPTER 2 – Porosity 2.7 A second textural parameter important for describing sediments is the grain size distribution or also known as sorting. Figure 2.8 illustrates the difference between excellent and poor sorting of sand grains. The top picture shows excellent sorting for both coarse and fine-grained rocks.
Igneous rocks that have bigger and clearly detectable crystals enclosed in a fine-grained matrix are called porphyry. Porphyritic texture arises when a number of the crystals increase significantly in size prior to the main mass of the molten rock crystalizing as a fine-grained uniform component.
Examples from the Web for . fine-grained Contemporary Examples of fine-grained At best, the artist gives us a fine-grained picture of her subjects, a picture that allows us to see them aright.
Dacite is a fine-grained igneous rock that is normally light in color. It is often porphyritic. Dacite is found in lava flows, lava domes, dikes, sills, and pyroclastic debris. It is a rock type usually found on continental crust above subduction zones, where a relatively young oceanic plate has melted below.

In many igneous rocks, large mineral crystals "float" in a fine-grained groundmass. The large grains are called phenocrysts, and a rock with phenocrysts is called a porphyry; that is, it has a porphyritic texture. Phenocrysts are minerals that solidified earlier than the rest of the rock, and they are important clues to the rock's history.
The white granite on the right has white K-feldspars. Both share a speckled appearance stemming from their coarse-grained textures. This close-up shows K-feldspars (pink), plagioclase (tan), quartz (gray), and amphibole (black). Click on the image for a hand-lens view of this sample. This is a relatively fine-grained granite.
