To: Mark Reed at Garnet From: ,"Robert B Symonds Vancouver, WA " (Bob Symonds) -------------------------------------------------------------------------------- Dear Mark, The 1979 Merapi gases are an excellent choice, and are reported correctly in the MSA paper. For trace elements you can use the condensate data from the 1987 GCA paper. These condensates were collected in 1984, but should be OK to combine with the 1979 gases. Here is the GASRUN file for the Merapi gas that I used for our 1987 paper. Bob MERAPI SAMPLE 79-2 FROM LE GUERN ET AL. (1982). MEAN CONDENSATE ANALYSIS FROM SYMONDS ET AL. (1987).
