The invention discloses a field geological information collection system. The field geological information collection system, a data transmission device, a system function module and a satellite imagemodule are included; and the system function module includes a project management module, a geological compass module, an image processing module and a character module. The determination of a collection point can use an isosceles triangle method, so that full covering on a target area can be determined; and through the combination of geological information distribution and mineral distribution,geological information characteristics of a mineral distribution area can be better analyzed.
