Tigers eye
Asbestos is a naturally occurring mineral fiber that is composed of six types of fibrous minerals: chrysotile, amosite, crocidolite, tremolite, anthophyllite, and actinolite. Chrysotile, amosite, and crocidolite are the most commonly used types of asbestos.
Fossils formed when silica is added are called silicified fossils. Silica replaces the original organic material of the organism, resulting in a preserved fossil with a glassy appearance. This process can produce detailed and well-preserved fossils.
Tiger's Eye, sometimes called crocidolite, is a form of quartz and can be found almost world-wide including Brazil, Russia, Japan, Scotland (UK) and SW Africa.

Tiger's eye (also called Tigers eye or Tiger eye) is a chatoyant gemstone that is usually a metamorphic rock that is yellow, red, and brown, with a silky luster.

Crocidolite is also known as blue asbestos. It is a type of asbestos mineral that is characterized by its blue color.
Asbestos is a naturally occurring mineral fiber that is composed of six types of fibrous minerals: chrysotile, amosite, crocidolite, tremolite, anthophyllite, and actinolite. Chrysotile, amosite, and crocidolite are the most commonly used types of asbestos.
The three main kinds of asbestos that have been used commercially are Amosite, Crocidolite, and Anthophilite.
Fossils formed when silica is added are called silicified fossils. Silica replaces the original organic material of the organism, resulting in a preserved fossil with a glassy appearance. This process can produce detailed and well-preserved fossils.
Chrysotile asbestos (White) is a Serpentine, Amosite (Grunerite) (Brown asbestos, and Crocidolite (Blue) are Amphiboles
Asbestos is composed of non biodegradable minerals including chrysotile, crocidolite, and amosite. So, Asbestos is non-biodegradable and it is toxic.
Crocidolite, a form of asbestos, was banned in most countries in the late 1970s and early 1980s due to its known health hazards, particularly its link to mesothelioma, a type of cancer. It is now recognized as a prohibited substance due to its well-documented risks to human health.
Tiger's Eye, sometimes called crocidolite, is a form of quartz and can be found almost world-wide including Brazil, Russia, Japan, Scotland (UK) and SW Africa.
Tiger's eye is formed through a process known as pseudomorphism, where silica replaces crocidolite (blue asbestos) fibers in the rock. This replacement process happens over many years due to the alteration of mineral deposits. The distinctive golden-brown color and chatoyancy of tiger's eye are a result of the fibrous nature of the crocidolite being replaced by quartz.
