weighed and archived. The non-ferromagnetic heavy mineral concentrate is then examined for indicator minerals and sometimes analysed geochemically. Indicator minerals are picked from samples during a visual scan, in most cases of the 0.25–0.5 mm and 0.5–2.0 mm fractions, and then analysed using an electron microprobe Fig. 1.

Assessment of Heavy Metals Contamination in Groundwater: A Case

6/12 · Heavy metals in groundwater were analyzed and their sources and impacts were identified using multivariate statistical tools and risk assessment. Three significant factors were extracted by factor analysis (FA), explaining 75.69% of total variance. These factors were in turn described by the clusters C3, C2 and C1, respectively, resulting from the cluster analysis (CA). Factor analysis and

The use of heavy mineral chemistry in reconstructing

Other relatively less common heavy minerals include epidote, monazite, and apatite. Epidote occurs in the sandstones of the Jhuran Formation and is yellow in colour with dominant irregular, and rare equant shapes. Monazite occurs as sub‐rounded to well‐rounded and is pale yellowish‐brown in colour.
