This study presents new geochemical (major and trace element, Nd–Sr isotope) and U–Pb zircon, monazite, titanite and rutile data for various rock types (eclogite, high-pressure granulite, amphibolite, orthogneiss, leucosome) of the high-grade metamorphic Mariánské Lázně Complex in the western Bohemian Massif.

Concordant U–Pb zircon analyses from the mafic to intermediate samples disclose the Mariánské Lázně Complex as a mixture of .

Metamorphic zircon in mafic rocks of the Mariánské Lázně Complex, as well as monazite from orthogneiss, and titanite in leucosome yield ages around 380 Ma.

On the basis of detailed petrography and cathodoluminescence imaging we conclude that the .

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.

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. Most absolute dating techniques are based on radioactive decay. Discovery of radioactivity in 1896 finally provided the elusive "rock clock".
