Studies of active geothermal systems show that a complete model of gold transport must include both dissolved and particulate forms. However, samples of the hydrothermal fluids are commonly spiked with aqua regia after collection in order to put any solids back into solution, thus preventing a quantitative assessment of the particle load. Although attempts have been made to filter the solids, gold nanoparticles (Au NPs) will mostly pass the 0.2-μm filters that are in common use, and a simple technique for analyzing suspended particles in the liquids has been lacking. In this study, we demonstrate how time-resolved acquisition of mass 197 in a conventional inductively coupled plasma-mass spectrometer (ICP-MS) can be used to detect and measure Au NPs in the filtered liquids, with an example of well-characterized fluids from the Reykjanes geothermal field on Iceland. The technique allows for precise monitoring of the solution as it is introduced into the plasma with the capability of identifying individual particles carried in suspension. Results show that Au particles passing the 0.2-μm filters are abundant in the studied samples, and measurements of the individual particles can be used to determine their size. The experiment highlights the potential of emerging ICP-MS techniques, including very fast data acquisition and multielement analysis of single particles in time-of-flight mode, for characterization of NPs in hydrothermal fluids.

Economic Geology

该杂志现为半季刊，由经济地质出版公司 (PUBCO) 于 1905 年首次出版，该公司是一家非营利性公司，旨在出版经济地质学期刊。 1920 年 SEG 成立时，PUBCO 和 SEG 之间的合作安排使该杂志成为该学会的官方机构，PUBCO 同意在封面上的“经济地质学家学会公报”标题下使用该学会的名称”。PUBCO 和 SEG 继续作为合作但独立的实体运营，直到 2001 年 PUBCO 董事会和 SEG 理事会一致同意批准正式的合并协议。PUBCO 董事会以前的活动是现在由出版委员会执行，这是 SEG 内的一个新的自治单位。

Economic Geology is a semi-annual journal first published by the Economic Geology Publishing Company (PUBCO) in 1905. PUBCO is a non-profit organization dedicated to publishing in the field of economic geology. In 1920, with the establishment of SEG, a collaborative arrangement between PUBCO and SEG made Economic Geology the official journal of the society, with PUBCO agreeing to use the title "Bulletin of the Society of Economic Geologists" on the cover. Since then, PUBCO and SEG have operated as collaborative yet independent entities until 2001, when the boards of PUBCO and SEG unanimously agreed to a formal merger. The functions previously held by the PUBCO board are now executed by the new autonomous unit within SEG known as the Publishing Committee.

《Economic Geology》是一本由经济地质出版公司（PUBCO）于1905年首次出版的半季刊。PUBCO是一家非营利性机构，专注于经济地质学领域的出版。1920年，随着SEG的成立，PUBCO与SEG之间建立了合作关系，使《Economic Geology》成为SEG的官方期刊。PUBCO同意在封面上使用“经济地质学家学会公报”的标题。自那时起，PUBCO和SEG作为合作但独立的实体继续运营，直到2001年，PUBCO董事会和SEG理事会一致同意正式合并。PUBCO董事会以前的职能现在由SEG内部的新自治单位——出版委员会执行。
