A small party landed after two hours' steaming, in search of quartz, which proved to be chloritic sandstones and limestones.
EN#30] Chloritic slate is the matrix of gold in the Brazil and in Upper Styria.
The main trunk of many branches, it is a smooth incline, perfectly practicable to camels; with banks and buttresses of green-yellow chloritic sands, and longitudinal spines outcropping from the under surface.
Some of the heights are of greenish-yellow chloritic felspar, well adapted for brick-making.
Here, however, they are hardly to be distinguished from the chloritic spines and natural sandbanks that stud the bed.
A thick layer of clay and mould rendered observation difficult; but a shelf of carburetted and shining slate seemed to me to indicate the presence of more ancient formations.
We asked them to explain to us this operation, which we had already seen practised in the missions of the Cataracts.
Mica-slate, chloritic slate and the rocks of slaty amphibole contain magnetic sand in the tropical regions of Venezuela, as in the most northern regions of Europe.
The Chloritic Marl in the Wealden district furnishes much phosphatic material, which has been extensively worked at Froyle.
Phosphatic nodules occur also in the Chloritic Marl of the Isle of Wight and Dorsetshire, and at Wroughton, near Swindon.
Twenty-one species of British Ammonites are recorded as found in the Gault, of which only eight are peculiar to it, ten being common to the overlying Chloritic series.
The higher portion of the Chloritic series in some districts has been called chloritic marl, from its consisting of a chalky marl with chloritic grains.
It belongs to the upper part of the Chloritic series, and is doubtless chiefly of animal origin, and may perhaps be partly coprolitic, derived from the excrement of fish and reptiles.
For, as the land went on sinking, and the cretaceous sea widened its area, white mud and chloritic sand were always forming somewhere, but the line of sea-shore was perpetually shifting its position.
The chloritic sand is regarded by many geologists as a littoral deposit of the Chalk Ocean, and therefore contemporaneous with part of the chalk marl, and even, perhaps, with some part of the white chalk.
Logan, which are of vast thickness, consisting chiefly of quartzite, with great masses of greenish chloritic slate, which sometimes include pebbles of crystalline rocks derived from the Laurentian formation, next to be described.
In this case and at Rat Island, the passage of the gneiss into imperfect hornblendic or into chloritic slate, seemed to be connected with the segregation of the veins of quartz.
Above the Chert beds is a band a few feet thick known as the Chloritic Marl, which shows a passage from sand to calcareous matter.
The Chalk Marl is well shown at Gore Cliff, sloping upwards from the flat ledges of the Chloritic Marl.
Secondary calcite also occurs here and in the chloritic pseudomorphs.
It was composed originally of fragments of a hemi-crystalline basic rock, of which the plagioclase phenocrysts have been replaced by calcite; whilst the augite and interstitial glass is now represented by viridite and a chloritic mineral.
The rhombic pyroxene is usually more or less converted into bastite which by further change passes into a chloritic material; whilst the augite sometimes undergoes the diallagic change resulting from schillerisation.
The scanty interstitial glass is converted into viriditic and chloritic materials.
The few pyroxene phenocrysts that once existed are now entirely represented by chloritic pseudomorphs.
The smallest is of greenstone, and the others of chloritic albite.
Such a one, of chloritic stone, found in a mound in Tennessee,[606] is in outline like Fig.
Where chlorite is important, it is sometimes called chloriticor "propylitic" alteration.
The chloritic phases are usually farther from the ore deposit than the sericitic phases, indicating less intense and probably cooler conditions of deposition.
This marly deposit passes in its turn into beds containing green particles of a chloritic mineral, called the upper greensand.
Professor Sedgwick supposes these porphyries to have originated contemporaneously with the stratified chloritic slates, the materials of the slates having been supplied, in part at least, by submarine eruptions oftentimes repeated.
The inferior division consists, for the most part, of clays and sands, called Greensand, because some of the sands derive a bright green colour from intermixed grains of chloritic matter.
The rocks of this group in South Devon consist, in great part, of green chloritic slates, alternating with hard quartzose slates and sandstones.
The above list will hopefully give you a few useful examples demonstrating the appropriate usage of "chloritic" in a variety of sentences. We hope that you will now be able to make sentences using this word.
