possibly formed through oxidative polymerisation of three alkadienes with the structure CH2=CH(CH2)nCH=CH(CH2)7-CH3 (n=15, 17 and 19) produced by Botryoaoaous braunii (ref. 206)

REMARKS - Coorongite, related to but probably not a direct precursor of Torban-ite, shows a pattern rather similar to that of Torbanite (Spectrum F.9). However, compared to Torbanite the maxima of each homologous ion series have shifted to a higher mass range, indicating longer average aliphatic chain lengths. Also the ion series at m/z 44, 58, 72, 86 and at m/z 46, 60, 74 are much more pronounced than in Torbanite, apparently indicating a higher abundance of oxygen-containing aliphatic compounds.
