Heavy mineral and zircon age constraints on provenance

2016-8-1  Heavy mineral and zircon age data demonstrate that in the Sherwood Sandstone Group of the Marchwood-1 and Southampton-1 boreholes, on the eastern margin of the Wessex Basin, sediment was supplied from both the south (Variscan highlands) and the east (recycled Old Red Sandstone). Interplay of these two sources led to a well-defined heavy mineral ...

Heavy-mineral analysis and typology of detrital zircons; a ...

Heavy-mineral analyses of Famennian and Visean Saxothuringian graywackes yielded stable, zircon-dominated spectra. The typology of the detrital zircons was examined using Pupin's typology method in order to test the application of that method to detrital zircons.

Detrital Zircon Perspectives on Heavy Mineral Sand

Greater zircon age heterogeneity correlates with heavy mineral enrichment. Enhanced heavy mineral yields reflect retention of resistate over labile minerals—a function of greater sediment transport, reworking, and upgrading processes that parallel those that result in detrital zircon age polymodality.

What is zircon? – TZMI

Zircon is the mineral name given to the compound zirconium silicate (ZrSiO 4).It is often found alongside other heavy minerals, most typically the titanium minerals ilmenite, rutile and leucoxene in which it can represent up to 50% of the mineral suite.

Heavy mineral analysis of Eocene sands and sandstones

2021-8-26  The heavy minerals (Figure 2) that are dominant in the sandstones are opaque minerals (O), zircon (Z), rutile (R), and tourmaline (T) while the sands have zircon, rutile, tourmaline, apatite (A) and staurolite (SQ). The heavy minerals present in these litho-units are continuously altered and gradually replaced by Table 1.

Heavy minerals, such as zircon, rutile, garnet, etc., can be applied to many applications. Zircon can be made to jewelry for decoration, and it is also an important material for casting, ceramic, glass and refractory industry. Zircon can also be smelted to be used in chemical and nuclear industries.
