The trench has been formed by the actions of the Romanche Fracture Zone, a portion of which is an active transform boundary offsetting sections of the Mid-Atlantic Ridge. [ 1 ] It was named after the French navy ship La Romanche , commanded by captain Louis-Ferdinand Martial which on 11 October 1883 made soundings that revealed the trench.
Some use the term "transform fault" to describe the seismically and tectonically active portion of a fracture zone after John Tuzo Wilson's concepts first developed with respect to the Mid-Atlantic Ridge. [2] The term fracture zone has a distinct geological meaning, but it is also used more loosely in the naming of some oceanic features.
The Blanco fracture zone is a fracture zone running between the Juan de Fuca Ridge and the Gorda Ridge. The dominating feature of the fracture zone is the 150 km (93 mi) long Blanco Ridge, which is a high-angle, right-lateral strike slip fault with some component of dip-slip faulting. [5]
The map has been checked against sea floor contours and at least one reference for position. Original acaedemic papers often are accurate sources, but data resolution has increased with time so improvements are possible. [1]

Bone healing, or fracture healing, is a proliferative physiological process in which the body facilitates the repair of a bone fracture. Generally, bone fracture treatment consists of a doctor reducing (pushing) displaced bones back into place via relocation with or without anaesthetic, stabilizing their position to aid union, and then waiting ...
Bone tissue is removed by osteoclasts, and then new bone tissue is formed by osteoblasts. Both processes utilize cytokine (TGF-β, IGF) signalling.In osteology, bone remodeling or bone metabolism is a lifelong process where mature bone tissue is removed from the skeleton (a process called bone resorption) and new bone tissue is formed (a process called ossification or new bone formation).
It was proposed that the fracture zone be renamed Gibbs fracture zone, as fracture zones are generally named for research vessels. The proposal was accepted only in part, and currently the official name is Charlie–Gibbs fracture zone. [8] Note that the double name refers to the two parallel fracture zones together.
