2011111ensp;0183;ensp;Heavy minerals occur in source rocks either as primary (like pyroxene) or as accessory components (e.g., zircon). Weathering regime, which acts upon the source rocks for a long period of time, removes detrital heavy minerals and transports through river channels eventually to the sea. Removed minerals
200511ensp;0183;ensp;Sources of heavy metals are mineral dusts, sea salt particles, extrater restrial matter, volcanic aerosols, forest fires, and industrial sources such as emissions from transportation, coal combustion, and fugitive particulate emissions . There are two major types of aerosols.
Heavy minerals were studied to determine the source of the deposits. Heavy mineral analyses revealed that zircon, tourmaline, rutile, garnet, amphibole, epidote, and apatite are the typical constituents of the heavy mineral fraction.

Heavy minerals are sensitive indicators of provenance. Over 30 translucent detrital species are of common occurrence, many of which have characteristic parageneses. However, because they are also sensitive to the processes of weathering, transportation, deposition and diagenesis, the heavymineral suite of an arenite does not necessarily
210ensp;0183;ensp;Heavy mineral suits represent the lithology of a source area more precisely than single minerals due to a large number of sourcesensitive minerals in the assemblages (Stattegger 1987). Mineral composition in the assemblage and its provenance have been used as an indicator of platetectonic setting as demonstrated by Pettijohn et al. ( 2012 ).

The heavy mineral fraction of sedimentary rocks and sediments can provide important information about provenance in sedimentary basins studies because some minerals or group of minerals can be traced to a source rock or terrain of specific composition. This work is a provenance study based on heavy mineral analyses of samples collected on the
The heavy minerals were mostly provided by the sublacustrine volcanic explosion that generated the tsunami. In such a sourcecontrolled environment, the abundance of heavy minerals is not grain size dependent, but rather closely related to successive waves
If there are lots of augite, magnetite, and olivine, then it probably comes from an igneous source. Heavy minerals are sorted out by a running water near the coastline at Pfeiffer Beach, California. A closer look at the Pfeiffer Beach sand. Main heavy mineral species are garnet, epidote, zircon, magnetite, spinel, staurolite, etc. Width of view 8 mm.
