What is paramagnetic rock dust?Well, let's start with paramagnetism. The soil in your organic garden is paramagnetic. It isn't magnetic, but is mildly attracted by a magnet and partially aligns with the earth's magnetic field, so it's paramagnetic. Some soils are attracted more than others, and generally, the more paramagnetic your soil is, the better.
Lodestone, a form of the mineral magnetite. Only certain minerals display magnetism or an attraction to a magnet. This would be one property of the mineral which would aid in its final identification.
If matter is attracted to a magnet, it is said to be paramagnetic. If the matter is repelled, it is said to be diamagnetic. There are big differences in degree of attraction and repulsion among various materials. The paramagnetism of many elements and compounds can be found in physics handbooks.

Abstract. Basalt is a common igneous rock and occurs on the surface of the earth with large abundance. Basaltic rock sources are formed from volcanic activities and their com positions vary from alkaline to tholeiitic and come under two classes: plateau basalts (ironrich) and cone basalts (ironpoor).
There are three basic types of rock: igneous, sedimentary, and metamorphic. Extremely common in the Earth's crust, igneous rocks are volcanic and form from molten material. They include not only lava spewed from volcanoes, but also rocks like granite, which are formed by .

a. Intrusive igneous rock – rock formed from the cooling and solidification of magma (beneath the Earth's surface). These rocks cool slowly and usually have large crystals and a coarsegrained texture. b. Extrusive igneous rock rock formed from the cooling of .
Igneous rocks can form underground when a pocket of magma cools. When melted rock is above ground, it is called lava. Igneous rock can also form above ground as lava cools after a volcano erupts.
As magnetitebearing igneous and sedimentary rocks form, the magnetite within them is aligned with the Earth's magnetic field. Since this rock magnetism, called paleomagnetism, does not change after the rock forms, it provides a record of what the Earth's magnetic field was like at the time the rock formed.
The Mineral magnetite. Magnetite is best known for its property of being strongly attracted to magnet s. Some forms of Magnetite from specific localities are in fact themselves magnets. Commonly known as Lodestone, this magnetic form of Magnetite is the only mineral that is a natural magnet. Due to the magnetism of Lodestone,...
Igneous rocks form from cooling bodies of magma. Over time, various weathering processes erode these rocks and the resulting particles or chemicals settle into beds and are compressed and cemented into sedimentary rocks. If these rocks are buried, heated and highly compressed they will be made into metamorphic rocks.

Igneous rocks can be easily identified with their texture, density, color and mineral composition. Its texture depends on upon the shape, size, time period to cool down and solidify and the arrangement of crystals in the rock.
The occurrence of magnetite is widespread. It is commonly found in igneous, and metamorphic rocks. Some sedimentary rocks have magnetite present in them as well. Large deposits are found in Kiruna, Sweden, the Adirondack area in New York, and the Pilbara region of Western Australia.

Metal Grains. These meteorites contain nickeliron metal in the form of tiny grains scattered throughout the matrix of the rock. If the stone is fresh and has a nice fusion crust it may not be desirable or necessary to cut it or grind off a spot to look for metal grains especially if the stone responds to a magnet.
Igneous rocks are rare in Arkansas, making up about % of the surface area of the state. Nonetheless, we find some interesting and unusual rocks and minerals within our igneous rocks. The above picture is a pseudohexagonal, zoned, green biotite crystal collected from Magnet Cove, Arkansas just last week.
Polarity of magnetic minerals can help date the igneous rocks, and thereby help date the fossilbearing sedimentary rocks nearby. If an igneous body has intruded through a sequence of sedimentary rock layers, that tells you the sequence is older than the igneous intrusion, and therefore the fossils are also older than the igneous intrusion.
