calcic

They show a preference for calcic waters and a tolerance to pollution.

Calcic plagioclase is stable to 25 km depth.

Peat mud and chalybeate bicarbonate calcic springs are used to treat patients.

Other rare varieties include troctolite which has a greater percentage of calcic plagioclase.

Calcic springs contained lime (calcium hydroxide).

However, basalt consists mostly of clinopyroxene (augite) and calcic plagioclase.

The agriculturally active area around Point Pedro with fertile calcic red latosols is known for its cotton production.

Rock formed almost entirely of calcic plagioclase feldspar (see below) is known as anorthosite.

Calcids have a calcic or petrocaalcic horizon and have carbonated in the layers above.

With an increase in calcic plagioclase and mafic minerals the rock type becomes a diorite.

The northern part of Thunnalai has calcic red latosols used for making pottery which was a cottage industry during 20th century.

Calcic Red-yellow latosols.

The mineralogy of basalt is characterized by a preponderance of calcic plagioclase feldspar and pyroxene.

The plagioclase is extremely calcic by terrestrial standards, with molar anorthite contents of 94-96% (An94-96).

The spectrum of 89 Julia shows the signature of silicate rich minerals with possible indications of an abundant calcic clinopyroxene component.

The resorts host many mineral springs with thermal (20-48 C), sulphuric, calcic, sodic, rich in bicarbonate waters known since the beginning of the millennium.

It consists essentially of major but variable amounts of olivine and calcic plagioclase along with variable minor pyroxene.

In contrast, the mafic minerals in this suite have low Mg/Fe ratios that are inconsistent with calcic plagioclase compositions.

Plagioclase phenocrysts often exhibit zoning with a more calcic core surrounded by progressively more sodic rinds.

It is a coarse grained rock consisting of 40 to 90% olivine along with significant orthopyroxene and lesser calcic chromium rich clinopyroxene.

In the feldspars the center is usually richer in calcium than the surrounding layers, and successive zones may often be noted, each less calcic than those within it.

It is highly calcic and is produced in a town called Ambaji (famous for its temple of Durga Devi).

Dissolution may be very subtle, with dissolution of calcic plagioclase whereas albite and potassium feldspar are not affected (Boles, 1984).

The amount of carbonates, however, is insufficient to meet the definition of a calcic horizon, or the upper boundary is more than 100 cm below the soil surface.

The dominant phenocrysts are zoned plagioclase, hypersthene, calcic clinopyroxene, titanomagnetite, and rimmed olivine.
