| description | This research investigates the composition of heavy minerals in the sedimentary
placer deposits of quartz sand from Singkawang and surrounding areas, West
Kalimantan Province. Quartz sand samples being investigated consist of ten (10) samples
collected from six (6) different locations. These sites at Mempawah river valley, Pasir
Panjang beach, southeast of Sambas, Bengkayang river, Monterado district, and south of
Singkawang city. This study aims to evaluate the potency of economic heavy minerals
contained within quartz sand deposits that exist in West Kalimantan. In addition, result of
study are also used interpret the relationship between geological conditions of
surrounding area with quartz sand mineralogy associations, and to investigate the
geological processes (transportation mode) that affect on sedimentary grain
characteristics. Analysis consists the preparation samples of quartz sand, splitting,
sieving, heavy mineral separation by panning, magnetic separation, microscopic analysis
and XRD analysis.
The results shows variations (species) of heavy minerals and their abundance
which are different from one study site to another location. Mempawah river valley shows
the presence of zircon, magnetite, rutile, hematite, pyrite, goethite, topaz, cassiterite,
epidote, aegirine, axinite, allanite and staurolite. Monterado district shows the presence
of zircon, rutile, ilmenite, topaz, chalcopyrite, goethite, epidote, aegirine, staurolite,
pyrite, hematite, axinite, sphene, hornblende, cassiterite and magnetite. Mempawah and
Monterado district have zircon mineral associations in large enough quantities is
possible because it has a source rock from Singkawang Batholith. Pasir Panjang beach
shows the presence of rutile, topaz, epidote, monazite, allanite, hornblende and zircon.
Heavy minerals are present in very small quantities because it is influenced by the
seawater wave activity. Southeast of Sambas shows the presence of rutile, topaz,
magnetite, zircon, aegirine, monazite, cassiterite, epidote, staurolite, hematite, pyrite,
allanite, molybdenite and chalcopyrite. Bengkayang river shows the presence of hematite,
rutile, cassiterite, ilmenite, magnetite, axinite, zircon, goethite, topaz, epidote, pyrite,
hornblende, staurolite and aegirine. Cassiterite found in large enough quantities from
Bengkayang because of other source rocks into sedimentary provenance of granitic rocks
S type. Area south of Singkawang city does not contain any heavy mineral. The
differences on the variation and abundance of heavy minerals are influenced by the
source rock and depositional environment.The mechanism of sedimentation processes
that produced quartz sand deposits in the study area consist of bedload transportation
(traction, rolling and saltation). |
