Called âone of the best and most consistent native trees for fall colorâ by tree expert Michael Dirr, the black tupelo is a terrific landscaping choice. Displaying various hues of yellow, orange, bright red and purpleâoften on the same branchâits foliage is a stand-out of the autumn season.
Types of Asbestos. The six minerals that make up the group called asbestos can be divided into two main types: amphibole and serpentine. Chrysotile asbestos is serpentine and it has fibers that are long and curly. This is the type of asbestos that has most often been used in construction and other industries.
For these reasons, asbestos has been used widely in many industries. Chemically, asbestos minerals are silicate compounds, meaning they contain atoms of silicon and oxygen in their molecular structure. Asbestos minerals are divided into two major groups: Serpentine asbestos and amphibole asbestos. Serpentine asbestos includes the mineral chrysotile, which has long, curly fibers that can be woven. Chrysotile asbestos is the form that has been used most widely in commercial applications. Amphibole asbestos includes the minerals actinolite, tremolite, anthophyllite, crocidolite, and amosite.
