hopane distributions are now routinely applied in assessing anoxia in ancient marine sediments and for oil-source correlation studies. Current parameters based on the extended hopanes focus on the predominance of the C~S 17a homologues (22s + R isomers), and thus reveal little information on the overall distribution. We present here a new method of characterising extended hopane distributions, using a combination of a CX:C\u0026X ternary diagram, and a hopane odd/even predominance parameter (HOEP). This allows the distinction of virtually all extended hopane distributions.","publication_date":"1995,,","publication_name":"Organic Geochemistry","grobid_abstract_attachment_id":"45061015"},"document_type":"paper","pre_hit_view_count_baseline":null,"quality":"high","language":"en","title":"A new method of comparing extended hopane distributions","broadcastable":true,"draft":null,"has_indexable_attachment":true,"indexable":true}}["work"]; window.loswp.workCoauthors = [31820419]; window.loswp.locale = "en"; window.loswp.countryCode = "SG"; window.loswp.cwvAbTestBucket = ""; window.loswp.designVariant = "ds_vanilla"; window.loswp.fullPageMobileSutdModalVariant = "control"; window.loswp.useOptimizedScribd4genScript = false; window.loswp.appleClientId = 'edu.academia.applesignon';</script><script defer="" src="https://accounts.google.com/gsi/client"></script><div class="ds-loswp-container"><div class="ds-work-card--grid-container"><div class="ds-work-card--container js-loswp-work-card"><div class="ds-work-card--cover"><div class="ds-work-cover--wrapper"><div class="ds-work-cover--container"><button class="ds-work-cover--clickable js-swp-download-button" data-signup-modal="{"location":"swp-splash-paper-cover","attachmentId":45061015,"attachmentType":"pdf"}"><img alt="First page of “A new method of comparing extended hopane distributions”" class="ds-work-cover--cover-thumbnail" src="https://0.academia-photos.com/attachment_thumbnails/45061015/mini_magick20190213-2604-1poeq6c.png?1550058196" /><img alt="PDF Icon" class="ds-work-cover--file-icon" src="//a.academia-assets.com/assets/single_work_splash/adobe.icon-574afd46eb6b03a77a153a647fb47e30546f9215c0ee6a25df597a779717f9ef.svg" /><div class="ds-work-cover--hover-container"><span class="material-symbols-outlined" style="font-size: 20px" translate="no">download</span><p>Download Free PDF</p></div><div class="ds-work-cover--ribbon-container">Download Free PDF</div><div class="ds-work-cover--ribbon-triangle"></div></button></div></div></div><div class="ds-work-card--work-information"><h1 class="ds-work-card--work-title">A new method of comparing extended hopane distributions</h1><div class="ds-work-card--work-authors ds-work-card--detail"><a class="ds-work-card--author js-wsj-grid-card-author ds2-5-body-md ds2-5-body-link" data-author-id="31820419" href="https://independent.academia.edu/PaulFarrimond"><img alt="Profile image of Paul Farrimond" class="ds-work-card--author-avatar" src="//a.academia-assets.com/images/s65_no_pic.png" />Paul Farrimond</a></div><div class="ds-work-card--detail"><p class="ds-work-card--detail ds2-5-body-sm">1995, Organic Geochemistry</p></div><div class="ds-work-card--button-container"><button class="ds2-5-button js-swp-download-button" data-signup-modal="{"location":"continue-reading-button--work-card","attachmentId":45061015,"attachmentType":"pdf","workUrl":"https://www.academia.edu/24731068/A_new_method_of_comparing_extended_hopane_distributions"}">See full PDF</button><button class="ds2-5-button ds2-5-button--secondary js-swp-download-button" data-signup-modal="{"location":"download-pdf-button--work-card","attachmentId":45061015,"attachmentType":"pdf","workUrl":"https://www.academia.edu/24731068/A_new_method_of_comparing_extended_hopane_distributions"}"><span class="material-symbols-outlined" style="font-size: 20px" translate="no">download</span>Download PDF</button></div></div></div></div><div data-auto_select="false" data-client_id="331998490334-rsn3chp12mbkiqhl6e7lu2q0mlbu0f1b" data-doc_id="45061015" data-landing_url="https://www.academia.edu/24731068/A_new_method_of_comparing_extended_hopane_distributions" data-login_uri="https://www.academia.edu/registrations/google_one_tap" data-moment_callback="onGoogleOneTapEvent" id="g_id_onload"></div><div class="ds-top-related-works--grid-container"><div class="ds-related-content--container ds-top-related-works--container"><h2 class="ds-related-content--heading">Related papers</h2><div class="ds-related-work--container js-wsj-grid-card" data-collection-position="0" data-entity-id="60609375" data-sort-order="default"><a class="ds-related-work--title js-wsj-grid-card-title ds2-5-body-md ds2-5-body-link" href="https://www.academia.edu/60609375/Rearranged_hopanes_in_sediments_and_petroleum">Rearranged hopanes in sediments and petroleum</a><div class="ds-related-work--metadata"><a class="js-wsj-grid-card-author ds2-5-body-sm ds2-5-body-link" data-author-id="45778889" href="https://independent.academia.edu/JMoldowan">J.
