The Virtual Rock Box

Mineral and Rock Identification

Earth Science 111,
Lab A - C & Exam 1

This "virtual rock box" is an online study tool to help you prepare for Labs A, B, C and the Rock and Mineral Identification exam in EASC 111. Use the navigation on the left to study the minerals and rocks in that category. Make sure you can identify the rock by studying the physical properties
and the photo. 

 

CAUTION:  These photos are not the same samples you will have on the exam.  Make sure
you go to the lab and look at several samples of the same mineral to see the variations each mineral might have.

Minerals A mineral is a naturally occurring, crystalline solid, having a distinct inorganic chemical composition. Some of the general properties of minerals that you should know are the hardness, color, streak color, luster, and cleavage. Study the 17 minerals in this virtual rock box See if you can guess the mineral before clicking on the image.

Igneous Rocks All igneous rocks form from the cooling and crystallization of
magma.  Igneous rocks are identified based on their texture
and composition.Textures include fine-grained, coarse-grained,
glassy, and porphyritic. Study the 6 types of igneous rocks in this
virtual rock box.

Sedimentary Rocks These rocks form in layers at Earth's surface from sediment (weathering products of pre-existing rocks).  They are identified based on particle size and compositionStudy

Metamorphic Rocks These rocks form from the alteration of pre-existing rocks due to increases in temperature, pressure, or a chemical reaction with nearby fluids.  Metamorphic rocks are identified based on their texture and composition.Textures are foliated and non-foliated.  Study the 5 types of sedimentary rocks in this virtual rock box.
