quartzose การใช้

• The term " quartzose sandstone " can also be used for a quartz arenite.
• Most outcrops are buff colored medium-grained, well-sorted quartzose sandstones.
• It is mostly composed of quartzose arenites.
• The uppermost stratum consists of of Triassic clayish quartzose turbidites interbedded with black slate and siltstone.
• It consists of micaceous mudstone that grades upward into a predominantly red quartzose, silty sandstone.
• The Rietvlei Formation consists of alternating horizons of light grey quartzose and feldspathic sandstone, siltstone and shale.
• The plateau predominantly consists of Triassic Hawkesbury Sandstone, which is largely quartzose sandstone with some shale and ironstone.
• Ganisters are indurated, fine-grained quartzose sandstones, which can be used in the manufacture of silica brick.
• By increase of quartz, aplites pass gradually, in a few localities, through highly quartzose modifications into quartz veins.
• The Taltung Formation is characterised by coarse-grained, volcaniclastic marine shales and fine-grained quartzose sandstones are observed.
• Medium grey to brown claystone makes up the majority of the formation, with lesser amounts of light grey to light brown quartzose sandstone.
• The stones were carved completely by hand from the quartzose sandstone quarries in the Dazhi ('Y魐 ) and Neihu areas of Taipei.
• In the central and southern outermost shelf, silt-sized quartzose materials form confined bodies referred to as the Arguin and Timiris Mud Wedges.
• It is found growing in shallow and sandy soils as part of woodland communities along with numerous other eucalypt species, on quartzose and sandstone ridges.
• The type specimen was found growing in mediacid ( pH 3.5 4.0 ) soil, on " quartzose mica-schist ledges ".
• The lowest division is a basal sandstone and conglomerate of quartzite, chert and gneiss pebbles and cobbles in a coarse-grained quartzose to arkosi sandstone matrix.
• The basal rocks of the Minfordd Formation contain clasts of granite, vein quartz, quartzitic sandstone, quartzose schists and were thought to be Cambrian basal conglomerate.
• Wolfram was discovered in 1894 in the headwaters of the Hodgkinson River scattered over the surface as bunches in quartzose boulders or in drifts interdispersed with coarse gravel.
• This is apparent in the absence of " Craspedia " from parts of western Tasmania which are characterised by soils derived from pre-Cambrian quartzose rock.
• As defined, ganisters can either be created by either the cementation of quartzose by surficial soil-forming processes to form silicrete or by diagenetic cementation within the subsurface.
