Geochemical potential field is defined as the scope within the earth’s space where a givencomponent in a certain phase of a certain material system is acted upon by a diffusion force,depending on its spatial coordinates X,Y,and Z. The three coordinates follow the relations: NF_ix=- NF, = -- ty’ NF. = -- tybx y 8y’ DzThe characteristics of such a field can be summarized as:(l) The summation of geochemicalpotentials related to the coordinates X,Y,Z or pseudo-velocity head, pseudo-pressure head andpseudo-potential head of a certain component in the earth is a constant as given by μ_x+μ_x+μ_x=corμ_(x2)+μ_(y2)+μ_(z2)=μ_(x1)+μ_(y1)+μ_(z1)Derived from these relations is the principle of geochemical potential conservation. Thefollowing relations have the same physical significance: μ_k+μ_k+μ_p=corμ_(k2)+μ_(u2)+μ_(P2) =μ_(k1)+μ_(u1)+μ_(p1)(2) Geochemical potential field is a vector field quantified by geochemical field intensity which isdefined as the diffusion force applied to one molecular volume (or one atomic volume) of acertain component moving from its higher concentration phase to lower concentration phase.The geochemical potential field intensity is given by E=-gradμRE=T RT RTE=_x--~RT i+_y--~RT j+_z--~RT K The present theory has been inferred to interpret the mechanism of formation of sometungsten ore deposits in China.
Geochemical potential field is defined as the scope within the earth’s space where a certaincomponent in a certain phase of a certain material system is acted upon by a diffusion force, depending on its spatial coordinates X, Y, and Z. The three coordinates follow the relations : NF_ix = - NF, = - ty ’NF. = - tybx y 8y’ Dz The characteristics of such a field can be summarized as: (l) The summation of geochemical potential entials related to the coordinates X, Y, Z or pseudo- velocity head, pseudo-pressure head and pseudo-potential head of a certain component in the earth is constant as given by μ_x + μ_x + μ_x = corμ_ (x2) + μ_ (y2) + μ_ (z2) = μ_ (x1) + μ_ (y1) + μ_ (z1) Derived from these relations is the principle of geochemical potential conservation. Thefollowing relations have the same physical significance: μ_k + μ_k + μ_p = corμ_ (k2) + μ_ (u2) + μ_ μ_ (k1) + μ_ (u1) + μ_ (p1) (2) Geochemical potential field is a vector field quantified by geochemical field intensity which is defined as the diffusion force applied t o one molecular volume (or one atomic volume) of acertain component moving from its higher concentration phase to lower concentration phase. The geochemical potential field intensity is given by E = -gradμRE = T RT RTE = _x-- ~ RT i + _y- - ~ RT j + _z-- ~ RT K The present theory has been inferred to interpret the mechanism of formation of some tungsten ore deposits in China.
