Claims
- 1. A method of geochemical prospecting for volatile substances associated with or produced by underground deposits wherein said volatile substances normally migrate to the earth's surface, said method comprising:
- preparing a plurality of shallow holes in the surface of the earth;
- placing an integrative sample collector in each shallow hole, each integrative sample collector comprising an adsorbent to adsorb said volatile substances;
- inverting a container over each integrative sample collector;
- backfilling each shallow hole;
- retaining the integrative sample collectors in the holes for a predetermibned time period to enable at least a portion of said volatile substances associated with underground deposit to be collected by said adsorbent;
- removing said integrative sample collectors after said predetermined time period has elapsed;
- analyzing a plurality of said volatile substances adsorbed on said adsorbent to obtain analytical data;
- storing said analytical data on a computer;
- objectively processing said analytical data by multivariate statistics so as to determine with some degree of confidence the nature of the underground deposit and calculating a similarity value based on the emanation of volatile substances from a known source comprising a known fingerprint; and
- mapping the distribution of similarity values to the known fingerprint so as to guide the exploration for the desired underground deposits.
- 2. The method defined in claim 1 wherein said placing step further comprises forming each of said integrative sample collectors as a ferromagnetic wire having said adsorbent bonded to one end thereof.
- 3. The method defined in claim 2 wherein said placing step further comprises mounting each of said ferromagnetic wire in a pedestal placed in said shallow hole, said ferromagnetic wire in a pedestal placed in said shallow hole, said pedestal supporting said ferromagnetic wire in spaced relationship to the earth in the shallow hole and the container inverted over the integrative sample collector.
- 4. The method defined in claim 2 wherein said placing step comprises mounting each of said ferromagnetic wire directly in the container.
- 5. The method defined in claim 2 wherein the placing step comprises forming each of said integrative sample collectors as a plurality of ferromagnetic wires each having a body of said adsorbent bonded to a respective end thereof, each ferromagnetic wire having a different length.
- 6. The method defined in claim 5 wherein said plurality of ferromagnetic wires have a plurality of adsorbents, each adsorbent being selected to collect and integrate a different set of volatile substances.
- 7. The method defined in claim 1 wherein the preparing step comprises forming said shallow holes in a predetermined pattern on the earth surface.
