However, the new rules can allow up to a dozen years to phase out the use of chrysotile asbestos in some manufacturing facilities. [26] The long phase-out period was a result of a strong lobby by Olin Corporation, a major chemical manufacturer, as well as trade groups like the U.S. Chamber of Commerce and the American Chemistry Council ...
The most common asbestiform mineral is chrysotile, commonly called "white asbestos", a magnesium phyllosilicate part of the serpentine group. Other asbestiform minerals include riebeckite, an amphibole whose fibrous form is known as crocidolite or "blue asbestos", and brown asbestos, a cummingtonite-grunerite solid solution series.
Antigorite is the polymorph of serpentine that most commonly forms during metamorphism of wet ultramafic rocks and is stable at the highest temperatures—to over 600 °C (1,100 °F) at depths of 60 km (37 mi) or so. In contrast, lizardite and chrysotile typically form near the Earth's surface and break down at relatively low temperatures ...
This is a list of free and open-source software for geological data handling and interpretation. The list is split into broad categories, depending on the intended use of the software and its scope of functionality. Notice that 'free and open-source' requires that the source code is available and users are given a free software license.
The Dortmund Data Bank [1] (short DDB) is a factual data bank for thermodynamic and thermophysical data. Its main usage is the data supply for process simulation where experimental data are the basis for the design, analysis, synthesis, and optimization of chemical processes.

Lizardite, chrysotile, and antigorite all have approximately the formula Mg 3 (Si 2 O 5)(OH) 4 or (Mg 2+, Fe 2+) 3 Si 2 O 5 (OH) 4, but differ in minor components and in form. [10] Accessory minerals, present in small quantities, include awaruite, other native metal minerals, and sulfide minerals. [12] Ophiolite of the Gros Morne National Park ...
