Obsidian: Characteristics and Properties. Obsidian is the result of volcanic lava coming in contact with water. Often the lava pours into a lake or ocean and is cooled quickly. This process produces a glassy texture in the resulting rock.Iron and magnesium give the obsidian a dark green to black color.ften the lava pours into a lake or ocean and is cooled quickly.

Report Abuse. Obsidian is an igneous rock. Any and all igneous rocks can turn into any and all metamorphic or sedimentary rocks. Obviously what it will 'turn into' down the line is dependent on it's location and the environment at that location, but location and environment are never permanent.The midwest used to be a huge ocean, etc.he rock cycle is really really simple. There are three types of rocks. Any of the three can turn into any of the other two types, but it takes a combination of some or all of the following: time, erosion, compaction, lithification, melting, or partial melting.
