Springs with both seasonal variation and little seasonal variation displayed Ce and Eu anomalies. The Ce and Eu anomalies along with the low LREE ratios can be indicative of shorter flow paths.\u00a0This discrepancy between REE results and flow classification could provide a useful complementary means for further understanding karst spring behavior.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>We collected samples from 16 spring in central PA and and an urban karst area just outside Philly and had them analyzed for REE.\u00a0 Rare earth elements (REE) have been used in previous studies to differentiate aquifer source rock and &hellip; <a href=\"https:\/\/sites.temple.edu\/geotoran\/2016\/07\/16\/new-ree-data-at-karst-springs\/\">Continue reading <span class=\"meta-nav\">&rarr;<\/span><\/a><\/p>\n","protected":false},"author":4114,"featured_media":0,"comment_status":"open","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[1],"tags":[],"class_list":["post-312","post","type-post","status-publish","format-standard","hentry","category-uncategorized"],"_links":{"self":[{"href":"https:\/\/sites.temple.edu\/geotoran\/wp-json\/wp\/v2\/posts\/312","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/sites.temple.edu\/geotoran\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/sites.temple.edu\/geotoran\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/sites.temple.edu\/geotoran\/wp-json\/wp\/v2\/users\/4114"}],"replies":[{"embeddable":true,"href":"https:\/\/sites.temple.edu\/geotoran\/wp-json\/wp\/v2\/comments?post=312"}],"version-history":[{"count":0,"href":"https:\/\/sites.temple.edu\/geotoran\/wp-json\/wp\/v2\/posts\/312\/revisions"}],"wp:attachment":[{"href":"https:\/\/sites.temple.edu\/geotoran\/wp-json\/wp\/v2\/media?parent=312"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/sites.temple.edu\/geotoran\/wp-json\/wp\/v2\/categories?post=312"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/sites.temple.edu\/geotoran\/wp-json\/wp\/v2\/tags?post=312"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
