K, Rb, Cs, Ba
What type of elements are Zr, Nb, Th, U classified as?
High field-strength elements (HFSE)
Which elements are more soluble in water than others?
Na, K, Ca
Peridotite is a rock forming the upper mantle due to its high content of which element?

Which elements accumulate in clastic sedimentary rocks according to the text?
Si, Fe, Al
Large ion lithophile elements (LILE) are easily accommodated by main mantle minerals.
False
Small ions carrying strong charges like Zr, Nb, Th, U, develop weak electrostatic fields.
False
Reservoirs in geochemistry refer to bodies of rock, water, and gas with compositions similar to other reservoirs.
False
Mantle composition has a high content of fusible elements like Na, K, Al.
False
Oceanic crust is enriched in elements that are insoluble like Si, Fe, and Al.
False
Magmatic melting contributes to geochemical fractionation among reservoirs by making all elements equally fusible.
False
Peridotite is a rock commonly found in the continental crust due to its high content of fusible elements.
False
Elements that are more soluble in water induce geochemical fractionation during erosion and sedimentation.
True
The composition of the continental crust is characterized by a high content of fusible elements.
True
Large ion lithophile elements (LILE) are known for their compatibility with main mantle minerals.
False
Test your knowledge on how charge and ionic radius of an ion define the ionic potential and help to divide elements geochemically. Learn about the large ion lithophile elements (LILE) and high field-strength elements (HFSE) in relation to their accommodation in minerals.
