What is the most common form of apatite?
Fluorapatite type
However, most of the fine crystals and collector specimens are of the Fluorapatite type, which is by far the most common form of Apatite.
What is the apatite family?
Apatite families can be described as a group of similar isomorphous hexagonal phosphate minerals. The main apatite group consists of Fluorapatite, Chlorapatite, and Hydroxylapatite. Sometimes it is quite difficult to distinguish between the individual members of the particular group.
Is apatite anisotropic?
Bone tissue has an anisotropic structure, associated with the collagen fibrils’ orientation and the c-axis direction of the bone apatite crystal.
Does apatite dissolve?
According to this model, apatite is dissolved by ionic detachment of calcium and orthophosphate ions from the surface to a solution.
What does apatite mean in biology?
Biological apatite is an inorganic calcium phosphate salt in apatite form and nano size with a biological derivation. It is also the main inorganic component of biological hard tissues such as bones and teeth of vertebrates.
What is the streak of apatite?

Which element r15 group is a part of apatite family?
phosphorous occurs in minerals of the apatite family. Hence,A is correct option.
How do you dissolve apatite?
What is apatite made of?
Apatites are phosphate minerals, and it is the association of the calcium ions that is responsible for the characteristic hexagonal crystal structure and morphology. Apatite is the mineral most often involved in replacing soft tissues and it does so with the highest degree of fidelity.
Why is apatite used to replace tissues?
Apatite is the mineral most often involved in replacing soft tissues and it does so with the highest degree of fidelity. Details, down to the subcellular level, such as Cretaceous fish cell nuclei sitting on muscle fibres, have been recorded and such fine detail is possible because the apatite crystallites can be very small (commonly <30 nm).
What is the relationship between apatite and collagen δ13 C?
Apatite and collagen δ13 C values were produced together in some early studies of modern and archaeological materials (e.g., DeNiro and Epstein, 1978b; Land et al., 1980; Sullivan and Krueger, 1981 ).
