ABSTRACT: The location of gold
veins, due to a slanting magma dike intrusion in a cold rock, considering earth
surface effects is determined. The 400°C and 500°C isotherm evolution resulting
from this magma intrusion are studied considering a 2-D model. In this
analysis, it is shown that the isotherm envelopes are the most important
surfaces. Analytic solutions have been found as a function of the angle a between the
dike and the vertical planes. The present results are more general than
previous ones in the contest of vertical dikes. Magma convection has been
considered in a simplified way. The agreement found that the results in the
work the actual vein sites at the gold mine, called Colombia, in the auriferous
area of El Callao, located 180 Km south of Ciudad Guayana in Bolivar state,
Venezuela, are much better than in previous works.
