Show Notes:
Geo 101 section:
– Earths structure, compositional boundaries, rheology boundaries and using seismology to figure it all out!

Ray paths of EQs through the earth note the bending in the outer core and the way it creates a gap on the surface that is the P-wave shadow!

Travel time curve poster from IRIS (group of seismology organizations) the colored dots are arrivals time is on the vertical axis and degree distance is on the horizontal axis.

Feature Mineral:
– crystal systems
– quartz (general)

Chalcedony: “Traditionally defined as a fibrous cryptocrystalline variety of quartz, more recently it has been shown that chalcedony is a mixture of quarts and moganite*, another silica mineral”
*I guess this one gets a post too!
Crystal system: Trigonal
Notes: concentrically banded its agate, layers/bands also called onyx, non banded forms (moss agate) and also its what replaces wood in petrified wood.

Check out that list! Its going to be a long post this one! First the general information and then I am going to pick it apart one at a time and for metaphysical stuff!

Cleavage: {0110} indistinct
Fracture: conchoidal fracture (characterized by smoothly curving surfaces)
luster: vitreous (glassy)
streak: white
Environment: sedimentary, metamorphic, AND igneous rocks!
crystal habit: crystalline (course and fine), druse (Crystal growth in a cavity which results in numerous crystal tipped surfaces)
color: brown, colorless, violet, gray, yellow, rose, green, orange….
crystal system: tiagonal
hardness: 7
optical properties: uniaxial
Quartz notes: Quartz is the most common mineral found on the surface of the Earth. A significant component of many igneous, metamorphic and sedimentary rocks, this natural form of silicon dioxide is found in an impressive range of varieties and colours. There are many names for different varieties.

Varieties*:
*what I really want to focus on here is what makes something “quartz” vs “chalcedony” vs “agate” for example, and I am going to make a separate post about varieties, there are just too many of them!
