All the economic and sub-economic porphyry copper systems exhibit LREE enrichment relative to HREE, whereas the economic deposits exhibit a relatively steep downward LREE to HREE profile, reflecting higher LREE abundance. The Eu anomalies vary from distinct negative in sub-economic deposits (Eu/Eu* ...
Silicon is the second most abundant element of the earth's crust; it makes up about 28% of the crust by weight. Oxygen, most abundant, makes up about 47%. Aluminum, third in abundance, makes up about 8%. Silicon is widely distributed, occurring in silica and silicates, but never ...
Rubidium is the 23rdmostabundant elementin the Earth's crust. Rubidium chloride is used in biochemistry as a biomarker to track where potassium is taken up by living organisms. The hyper-fine electron structure of Rubidium-87 is used in some atomic clocks to maintain accuracy. ...
