Distinguishing Characteristics: Visible crystals of pink feldspar, white or grey quartz, and black mica. There is no horizontal banding in granite. Origin of your Samples: Belmont Township, Ontario
Cleavage: good - observe feldspar’s cleavage by holding the mineral up to the light and turning it slowly to see the slick, flashy surface where light reflects off the sample. Relative Density: 2.5. Distinguishing Characteristics: pink colour and cleavage. Origin of your Samples: Bancroft, Ontario.

China has pale green and pink soapstone, while Russia and Alaska produce a black variety. Montana is the source of soapstone with the look of moss growing through it, and the eastern townships of Quebec provide dark green and black specimens. Mining Matters thanks Canadian sculptor Sandy Cline for sharing some of his
approximately 300 kilograms of beautiful pink granite. Mining Matters educational resources have a huge need for this eye-catching rock; to teach participants about the bedrock of our country, the relationship between rocks and minerals. This granite is a central component of many lessons. Incorporating samples into our resource kits is
of pink to buff in the final product. What is an advantage of using Brick? Brick provides energy savings because it has a high thermal mass. A high thermal mass means that brick can absorb the sun's radiation, store the energy and release it later. This delays the transmission of outside temperature extremes through to the
Quartz with impurities presents a range of varieties and colours, e.g., purple (amethyst), pink (rose quartz), and yellow or orange (citrine). When quartz-bearing rocks get eroded, weather-resistant quartz grains get carried to deposits in soil, in rivers, and on beaches as sand. Deposits also used.
The three main minerals are orthoclase (pink feldspar), quartz (clear, white or-gray, glassy) and mica (black and flaky). Sometimes the mineral hornblende (black and hard, not provided in this kit) is also present. Rhyolite. Fine grains (less than 1mm) show that it is a volcanic rock.
Soil is a complex mixture of mineral matter (gravel, sand, silt and clay), organic matter (like humus – that, incidentally gives the name to our species as being “human”, or “from the soil”), water, air and living organisms. Mineral matter can be divided into separate components based on grain size.
