Quantitative analyses of carbon in anhydrous and hydrated interplanetary dust particlesCarbon is an important and significant component of most anhydrous and hydrated IDP's. We have analyzed approx. 40 anhydrous and hydrated chondritic IDP's for major and minor elements, including C and O. Quantitative analyses of light elements in small particles are difficult and require careful procedures in order to obtain reliable results. In our work, we have completed extensive analytical checks to verify the accuracy and precision of C abundances in IDP's. In our present work, additional methods are used to verify C abundances in IDP's including analysis of IDP thin sections embedded in S, and direct observation of carbonaceous material in thin sections. Our work shows conclusively that C is strongly enriched in IDP's relative to CI abundances.
