Mineral Hand Samples
This common mineral displays conchoidal fracture.
What is Quartz
This seismic wave is the fastest one to travel to the earth's surface from the focus
What is P-waves.
This is the relative grain size of plutonic rocks.
What is coarse?
This category of sedimentary rock is made by the transportation and deposition of fragments of rocks and minerals.
What is clastic.
This type of metamorphism involves only changes in temperature.
What is contact metamorphism.
This principle details the order in which minerals crystallize from a magma
What is Bowen's Reaction Series
This is the number of seismic stations that you need to provide data to determine the precise location of an earthquake
What is three
This type of fine-grained rock is the most abundant igneous rock at Earth's surface.
What is basalt.
This category of sedimentary rock reflects the involvement of once living organisms in its formation.
What is biochemical.
This is the protolith of garnet-mica schist
What is a shale
The formula of this mineral is (Mg, Fe)2SiO4.
What is olivine
This geologic hazard arises when unconsolidated sediment with water between the grains begins to shake
What is liquefaction
The presence of this substance lowers the melting temperature of rocks.
What is water.
This sedimentary rock has lots of angular chunks in a fine grained matrix
What is a breccia
This is type of diagram shows stability fields of different minerals
What is a phase diagram
Double chains of linked silica tetrahedra constitute this group of minerals.
What are amphiboles.
When movement occurs along a fault, this is property of the system lessens
What is energy
This location on Earth was once the site of a continent-continent collision zone
What is the Appalachian mountains
This type of sedimentary structure indicates deposition on the seafloor after sediment comes tumbling down a continental slops.
What is graded bedding
The presence of blue amphiboles in a schist indicates this P-T condition of metamorphism.
What is very high pressure and moderate temperature.
These minerals are alumino-silicate polymorphs useful for determining pressure and temperature of rock formation.
What are sillimanite, kyanite, and andalusite.
This hazard arises when an earthquake occurs under the ocean
What is a tsunami
This type of igneous melt is likely to erupt explosively at the surface of the earth
What is rhyolite
This sedimentary rock is made up of layers of calcite that rolled around on the seafloor and forms like a snowball.
What is an oolitic limestone
This metamorphic texture is formed by alignment of micas in the rock
What is schistosity
