In order to clarify the relationship between fractures and gas accumulation, using data of cores, image logs and experimental analysis, we analyzed the fracture genetic types, development characteristics, controlling factors, distribution rules and formation periods. And then, by combining the evolution of source rock, activity periods of gas source faults and the evolution of cap rock sealing

Volcanic rock (often shortened to volcanics in scientific contexts) is a rock formed from lava erupted from a volcano.In other words, it differs from other igneous rock by being of volcanic origin. Like all rock types, the concept of volcanic rock is artificial, and in nature volcanic rocks grade into hypabyssal and metamorphic rocks and constitute an important element of some sediments and

;Abstract: It is important to date the Quaternary volcanic rocks for understanding the neotectonic activities in Hebei plain. The 500.25 meter drill hole CK3 located near Haixing Country of Hebei Province revealed 4 layers of volcanic rocks. The 40Ar/39Ar age of the first stage of Quaternary volcanic rocks is 2.36±0.05 Ma.

Igneous rock - Igneous rock - Classification of volcanic and hypabyssal rocks: Owing to the aphanitic texture of volcanic and hypabyssal rocks, their modes cannot be readily determined; consequently, a chemical classification is widely accepted and employed by most petrologists. One popular scheme is based on the use of both chemical components and normative mineralogy.

This information helps them to classify the rock and may give them direct clues about the volcano and the eruption that formed the rock. Lava solidifies to rock. New Zealand has 3 main types of volcanoes, and each has been formed from a different type of magma. Once the lava has erupted, it cools and solidifies into rock:
