Orthoclase feldspar is a mineral that commonly occurs in certain intrusive
igneous rocks that crystallize from melts deep within the crust of the earth.
The chemical formula for orthoclase is KAISİ3O3 and its molecular weight is
278.4 g/mol. Most potassium in orthoclase is 39K (93.2581%). However,
.0117% of naturally occuring potassium is 40K (which is unstable with a half-
life of 1.28x109 yr). When orthoclase-bearing igneous rocks form, the ortho-
clase crystallizes and its chemical constituents are locked in the crystal
structure, no longer able to be freely exchanged with their environment. As
this happens, the 40K in the orthoclase continues to decay according to
40K → 40Ar + e* + Ve
The decay produces 40Ar, but the argon remains trapped in the rigid
crystal structure. As time passes, argon accumulates in the crystal structure.
Many years after the crystallization of the igneous rock, a crystal of ortho-
clase from the rock may be extracted so that its argon content can be…
Polonium, the Period 6 member of Group 6A(16), is a rare radioactive metal that is the only element with a crystal structure based on the simple cubic unit cell. If its density is 9.142 g/cm³,calculate an approximate atomic radius for polonium.
Fluids were sampled from surface manifestations within a geothermal system. Laboratory analysesresulted to the following concentrations:
Silica quartz = 500 ppm
Amorphous silica = 1000 ppm
Sodium = 1000 ppm
Potassium = 200 ppm
Magnesium = 0.2 ppm

- A 10 cm long core sample with a 1 inch (2.54 cm) diameter is sampled from a reservoir. Unfortunately, during transportation some portion of the sample is cracked and lost. Now the sample is not a perfect cylinder and it is not possible to cut a cylinder sample from the rest of the sample. The core sample is cleaned for porosity analysis. The mass of the core sample is measured as 100 g. The core sample is placed in cell two of a Boyle's Law device (Helium porosimeter). Each of the cells has a volume of 200 cc. Cell one is pressured to 100.0 psig. Cell two is evacuated. Then, the cells are connected and the resulting pressure is 48 psig.
