This is either a greenstick fracture or a longitudinal fracture depending upon exactly how the bone breaks.
A mineral with fracture has uneven side when split into half.
A bone fracture where the bone fragments are driven into each other is called a "Compacted Fracture".
shear fracture.

After 5 half-lives, 3.125% (or 1/2^5) of a radioactive sample remains. Each half-life reduces the sample by half, so after 5 half-lives, there is only a small fraction of the original sample remaining.
A broken bone is often called a "fracture" or "bone fracture". Some examples from the Wikipedia entry on bone fracture. * Complete Fracture- A fracture in which bone fragments separate completely. * Incomplete Fracture- A fracture in which the bone fragments are still partially joined. * Linear Fracture- A fracture that is parallel to the bone's long axis. * Transverse Fracture- A fracture that is at a right angle to the bone's long axis. * Oblique Fracture- A fracture that is diagonal to a bone's long axis. * Compression Fracture-A fracture that usually occurs in the vertebrae. * Spiral Fracture- A fracture where at least one part of the bone has been twisted. * Comminuted Fracture- A fracture causing many fragments. * Compacted Fracture- A fracture caused when bone fragments are driven into each other * Open Fracture- A fracture when the bone reaches the skin * Bug fracture- A fracture when the bone is in place, but the fracture has the appearance of a crushed insect.
Yes, anthracite does have a distinct fracture. It tends to break with a conchoidal fracture, meaning it produces smooth, curved surfaces when fractured.
After 5 half-lives, 3.125% of the original carbon-14 would remain. Each half-life reduces the amount by half, so after 5 half-lives, it would be reduced by a factor of 2^5 = 32.
