These inclusions are trapped gases, liquids or crystals, either trapped singularly (one-phase) or as a heterogeneous mixture of more than one phase (multi-phase) in a single cavity. Depending upon the timing of entrapment of liquid in the crystals, fluid inclusions are classified as primary, secondary or pseudosecondary. The inclusions occur either as isolated, clustered, or trail bound; those occurring in groups form the Group of Synchronous Inclusions (GSI) having similar composition and time of entrapment. The composition of trapped fluid varies greatly; commonly detected constituents include H 2 O, CO 2 , CH 2 , H 2 S, Cl, Br, F, I, N 2 , S, Na, K, Ca, Mg and Fe. There are several instruments used in the study of fluid inclusions, but the basic study is carr...

Research paper thumbnail of Understanding the Behaviour of Rare Earth Elements in Minerals and Rocks

Rare earth elements or lanthanides comprised a series of elements between La (57) and Lu (71), ... more Rare earth elements or lanthanides comprised a series of elements between La (57) and Lu (71), show remarkable similarity in their oxidation states (3+) and chemical properties. The trivalent REEs show significant substitution for Mn2+, Ca2+, Y3+, Th4+ and Zr4+; which greatly influences their partitioning in various mineral phases, such as plagioclase, allanite, apaptite, monazite and zircon. The partitioning of REEs in mineral/melt systems had been thoroughly investigated, and as such their partition coefficients in different types of magma are now available. Study of magmatic rocks provides valuation information on their mantle source regions; viz. degrees of partial melting, fractionation, heterogeneity, assimilation or contamination and metasomatism. On the other hand, REEs do not fractionate readily during sedimentation, nevertheless, a remarkable uniformity is observed in the REE patterns of sedimentary rocks. Weathering processes are however, known to fractionate REEs. In case of metamorphic rocks, the protolith composition and P-T-X conditions influence distribution and mobility of REEs. Behavior of REEs in Palaeogene-Neogene-Holocene systems depends on the media being samples, e.g. volcanic rocks, pyroclastic products mostly volcanic ash, wind-borne sediments and alluvial soils. With the proper understanding of the system being investigated, REEs may prove to be useful tracer of a wide range of petrogenetic processes.

There are several instruments used in the study of fluid inclusions, but the basic study is carried out using heatingfreezing stages and Laser Raman Microprobe. The study of f luid inclusions reveal geologically important information such as temperature, pressure, salinity, density and depth of trapping; and thereby provide direct information about the conditions at which given minerals and rocks are formed.
