Mineralogical analysis was performed by means of optical microscopy and whole rock chemical compositions of the samples were determined by X-ray fluorescence (XRF) spectrometry. Results of analyses show that lizardite is predominant serpentine mineral present, followed by chrysotile and trace amount of magnetite. Remnants of olivine and pyroxene were detected in some samples but they have been pseudomorphically replaced by serpentine. Serpentinization of Sulawesi ultramafic rocks has led to transformation of olivine and lesser pyroxene become secondary phases mainly lizardite and minor chrysotile. This process also has changed the properties of rocks such as reduction in grain size and decreasing in density. Relatively higher MgO concentration combined with fine grained and porous rocks indicate that some Sulawesi ultramafic rocks are good candidate as the host for mineral carbonation. Fosteritic olivine and serpentine (lizardite) are the most soluble Mg-rich minerals in acid. Carbonation may occurs where Mg<jats:sup>2+<\/jats:sup> readily reacts with CO<jats:sub>2<\/jats:sub> forming thermodynamicly stable magnesite (MgCO<jats:sub>3<\/jats:sub>)<\/jats:p>","DOI":"10.1088\/1755-1315\/589\/1\/012024","type":"journal-article","created":{"date-parts":[[2020,11,19]],"date-time":"2020-11-19T03:59:27Z","timestamp":1605758367000},"page":"012024","update-policy":"https:\/\/doi.org\/10.1088\/crossmark-policy","source":"Crossref","is-referenced-by-count":4,"title":["The nature of ultramafic rocks from Sulawesi, Indonesia and their suitability for CO<sub>2<\/sub> sequestration"],"prefix":"10.1088","volume":"589","author":[{"family":"Sufriadin","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"S","family":"Widodo","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"M","family":"Thamrin","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"A","family":"Maulana","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"A","family":"Ito","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"T","family":"Otake","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"266","reference":[{"key":"EES_589_1_012024bib1","first-page":"364","article-title":"Carbon dioxide sequestration by mineral carbonation technology: A state-of-the-art review","volume":"109","author":"Olajire","year":"2013","journal-title":"Journal of Petroleum Science and Technology"},{"year":"2017","author":"Olivier","key":"EES_589_1_012024bib2"},{"key":"EES_589_1_012024bib3","first-page":"53","article-title":"Assessment of carbon dioxide sequestration potential of ultramafic rocks in the greenstone belt of southern India","volume":"94","author":"Mani","year":"2008","journal-title":"Current Science"},{"key":"EES_589_1_012024bib4","doi-asserted-by":"crossref","first-page":"399","DOI":"10.2138\/rmg.2013.77.11","article-title":"Geochemical Monitoring for Potential Environmental Impacts of Geologic Sequestration of CO2","volume":"77","author":"Kharaka","year":"2013","journal-title":"Geochemistry of Geologic CO2 Sequestration, Reviews in Mineralogy & Geochemistry"},{"key":"EES_589_1_012024bib5","doi-asserted-by":"crossref","first-page":"73","DOI":"10.1016\/j.chemer.2014.09.003","article-title":"Petrology, geochemistry and tectonic significance of serpentinized ultramafic rocks from the South Arm of Sulawesi, Indonesia","volume":"75","author":"Maulana","year":"2015","journal-title":"Chemie der Erde"},{"key":"EES_589_1_012024bib6","doi-asserted-by":"crossref","first-page":"55","DOI":"10.1016\/j.tecto.2004.04.008","article-title":"Petrology, geochemistry and paleogeographic reconstruction of the East Sulawesi Ophiolite, Indonesia","volume":"392","author":"Kadarusman","year":"2004","journal-title":"Tectonophysics"},{"key":"EES_589_1_012024bib7","doi-asserted-by":"crossref","first-page":"486","DOI":"10.1038\/345486b0","article-title":"CO2 disposal by means of silicates","volume":"345","author":"Seifritz","year":"1990","journal-title":"Nature"},{"key":"EES_589_1_012024bib8","doi-asserted-by":"crossref","first-page":"81","DOI":"10.1046\/j.1526-0984.1998.08014.x","article-title":"Carbon dioxide sequestering using ultramafic rocks","volume":"5","author":"Goff","year":"1998","journal-title":"Environmental Geoscience"},{"key":"EES_589_1_012024bib9","doi-asserted-by":"crossref","first-page":"115","DOI":"10.2113\/gselements.9.2.115","article-title":"Serpentinite carbonation for CO2 sequstration","volume":"9","author":"Power","year":"2013","journal-title":"Element"},{"key":"EES_589_1_012024bib10","doi-asserted-by":"crossref","first-page":"1389","DOI":"10.1016\/j.apenergy.2017.09.015","article-title":"A review of developments in carbon dioxide storage","volume":"208","author":"Aminu","year":"2017","journal-title":"Applied Energy"},{"key":"EES_589_1_012024bib11","doi-asserted-by":"crossref","first-page":"8049","DOI":"10.1039\/C4CS00035H","article-title":"A review of mineral carbonation technologies to sequester CO2","volume":"43","author":"Sanna","year":"2014","journal-title":"Chem.
