It is India's smallest state by area and the fourth smallest by population.Goa has the highest GDP per capita among all Indian states, that is two and a half times that of the country.

Metamorphic rocks that formed at very high pressures, such as eclogites and high-pressure granulites, are the most important witnesses of the tectonothermal processes that happen within the generally inaccessible lower crust and lithospheric mantle.
Studies of these kinds of high-pressure rocks, however, are hampered by the difficulty of precisely determining the age of the high-pressure event, and thus constraining the geodynamic evolution and tectonic setting in which these rocks formed.
Similarly, low magnesium komatiitic meta-basalts (8–10% Mg O) from Barberton have a similar range and mean of δO values to those of greenschist facies meta-basalts on the modern ocean floor.
Variations in the major and trace element contents between margins and cores of komatiitic basalt pillows show that the elements analysed can be divided into two groups.The historic city of Margao still exhibits the cultural influence of the Portuguese, who first landed in the early 16th century as merchants and conquered it soon thereafter.Goa is a former Portuguese province; the Portuguese overseas territory of Portuguese India existed for about 450 years until it was annexed by India in 1961.540 Ma oceanic rocks juxtaposed at depth with lower-crustal rocks of the structurally overlying Teplá–Barrandian Unit.This interpretation refutes earlier models in which the Mariánské Lázně Complex was interpreted as a dismembered Cambro-Ordovician ophiolite complex affected by Variscan subduction.Oxygen isotope, major and trace element data have been obtained on a suite of rocks and minerals from the Barberton greenstone belt, South Africa.
