Exploration for Granite-Hosted Tantalum Deposits: An Approach via District Analysishnique involves the collection, collation and synthesis of data concerning specific characteristics of the deposits, and allows exploration attention to be focussed quickly on areas where there is the maximum chance for successful discovery. The major features of granite-hosted tantalum deposits whi

Geochemical Evaluation of the Tantalum Potential of Pegmatitesegmatites very often occur in large swarms scattered over a wide area (e. g. Tantalite Valley, Namibia; Manitoba, Canada). Since not all pegmatites in such swarms are tantalum-bearing, many attempts have been made to distinguish pegmatites of economic interest from barren ones. This chapter presents

P. J. Pollardms. Hh proteins are secreted ligands synthesized in discrete regions. The receptor of Hh is Patched (Ptc) and it is expressed in the cells close to the source of Hh. Ptc binds the ligand and transduces a signal which is modulated depending on the context and the concentration of Hh received. Hh and
