Crystal structure analysis shows there can be no further doubt regarding the existence of the carbonate apatite or oxy-apatite molecules. Chemical analysis is given of the dahllite from Mouillac, France, upon which x-ray measurements were made.
H042 The application of airborne electromagnetics to mineral groundwater and petroleum exploration. 1 RICHARD S. SMITH AND DOUG MCCONNELL Fugro Airborne Surveys. Airborne electromagnetic (AEM) systems were developed more than 50 years ago to explore for mineral deposits. Electromagnetic systems primarily respond to the conductivity (or the resistivity) of material in the earth. Their primary success has been for discovering highly conductive massive sulphide bodies located in areas such as the Canadian and Fennoscandinavian shields. Recent examples include the Perseverance deposit in Canada and the Storliden Deposit in Sweden. Currently there is great interest in looking for conductive kimberlites (hopefully
