This soil sample was removed from the subsoil of a trial pit at the Arthur Rickwood Experimental Husbandry Farm, Mepal Fen, Cambs.  Oxidation has been brought about by drainage of the land for agriculture and associated features are strong acidity (pH less than 4) caused by the release of sulphuric acid, orange-coloured deposits of ochre in drainage pipes and drains, and aluminium toxicity causing a stunted, deformed root system.  Soils with strong acidity formed by this process are known as 'acid sulphate soils'; they are common in the perimarine zone of the Fenland of Eastern England where the original sulphides were supplied by a series of marine transgressions.  Jarosite is a prominent feature of mineral sediments such as the Fen Clay but is absent from fen peat which also experiences strong acidification in these areas.","Rodney Burton",480,640,{"id":663,"source_url":664,"license_code":591,"credit_html":665,"title":666,"description":667,"author":668,"original_width":669,"original_height":669},12537,"https:\u002F\u002Fcommons.wikimedia.org\u002F?curid=1956114","Dave Dyet http:\u002F\u002Fwww.shutterstone.com http:\u002F\u002Fwww.dyet.com, via \u003Ca href=\"https:\u002F\u002Fcommons.wikimedia.org\u002F?curid=1956114\" rel=\"noopener\">Wikimedia Commons\u003C\u002Fa>","Jarosite on quartz Potassium iron sulfate Arabia District, Pershing County, Nevada 2779.jpg","These mineral images are free to use how you wish.","Dave Dyet http:\u002F\u002Fwww.shutterstone.com http:\u002F\u002Fwww.dyet.com",700,{"id":671,"source_url":672,"license_code":532,"credit_html":673,"title":674,"description":675,"author":676,"original_width":677,"original_height":678},61452,"https:\u002F\u002Fcommons.wikimedia.org\u002F?curid=7049038","Ra'ike (see also: de:Benutzer:Ra'ike), via \u003Ca href=\"https:\u002F\u002Fcommons.wikimedia.org\u002F?curid=7049038\" rel=\"noopener\">Wikimedia Commons\u003C\u002Fa>","Jarosit - Sierra Almagrera, Spanien.jpg","\u003Ca href=\"https:\u002F\u002Fen.wikipedia.org\u002Fwiki\u002FJarosite\" class=\"extiw\" title=\"en:Jarosite\">Jarosite\u003C\u002Fa> - Locality: Sierra Almagrera, Spain - Exposed in the Mineralogical Museum, Bonn, Germany","Ra'ike (see also: de:Benutzer:Ra'ike)",1550,950,{"id":680,"source_url":681,"license_code":532,"credit_html":682,"title":683,"description":684,"author":685,"original_width":527,"original_height":686},12541,"https:\u002F\u002Fcommons.wikimedia.org\u002F?curid=14865670","Christian Rewitzer, via \u003Ca href=\"https:\u002F\u002Fcommons.wikimedia.org\u002F?curid=14865670\" rel=\"noopener\">Wikimedia Commons\u003C\u002Fa>","Jarosite-114913.jpg","\u003Ca href=\"https:\u002F\u002Fen.wikipedia.org\u002Fwiki\u002FJarosite\" class=\"extiw\" title=\"en:Jarosite\">Jarosite\u003C\u002Fa>\n\u003Cdl>\u003Cdd>\u003Cdl>\u003Cdd>Locality: Jaroso Ravine, Sierra Almagrera, Cuevas de Almanzora, Almería, Andalusia, Spain\u003C\u002Fdd>\n\u003Cdd>Picture width 2 mm.

small yellow flower gave this mineral its name. *Jara* is the Spanish word for a yellow-flowered shrub of the genus *Cistus* that grows across the dry hills of southern Spain[1]. One ravine thick with it, the Barranco del Jaroso in the Sierra Almagrera, became the place where the mineral was first found.\n\nIn 1852 the German mineralogist Johann Friedrich August Breithaupt described jarosite from that ravine and named it for the locality[2]. The site sits near Cuevas del Almanzora in Almería, in Spain's far south. The mineral is a sulfate — a compound built around sulfate groups — of potassium and iron, and it forms in acidic, iron-rich settings where sulfide ores have weathered.\n\nPeople had brushed against the mineral long before they named it. Clay spheres coated in jarosite were found buried beneath the Temple of the Feathered Serpent at Teotihuacan in central Mexico[3].\n\nFor most of the next century after Breithaupt, jarosite stayed a minor curiosity of mine dumps and weathered outcrops. Then a robot found it on another planet.\n\nIn 2004 the rover *Opportunity* detected jarosite at Meridiani Planum, the broad Martian plain where it had landed[4]. The find came from the rover's Mössbauer spectrometer, an instrument that identifies iron-bearing minerals[4]. The detection mattered because jarosite forms only in dilute sulfuric acid in groundwater[5]. Its presence was strong evidence that acidic liquid water had once stood on the Martian surface. The geologist Roger Burns had predicted the find years earlier[5]. *Spirit* and *Curiosity* later detected the same mineral elsewhere on Mars[6].","claude-opus-4-8","1.7.0",{"markdown":974,"model_version":971,"prompt_version":972,"reviewed_at":11},"Almost nobody mines jarosite. It has no role as a gemstone, a pigment of any scale, or an ore, and it is not a sought commodity. Where it matters to industry, it appears as a waste product rather than a goal.\n\nThat role is in zinc refining. Extracting zinc from its ore by chemistry rather than smelting — a route called hydrometallurgy — leaves dissolved iron in the liquid, and the iron must come out before the zinc can be recovered. The standard way to remove it is the jarosite precipitation process, the most extensively used iron-removal method in the industry[1]. Iron is forced to crystallise out of the weakly acidic solution as jarosite[1]. The resulting solid cake is pulled from the circuit and stockpiled as a tailing — mine waste held on site[1].\n\nThe volumes are large, which makes disposal the real story. Roughly half a tonne of jarosite residue is generated for every tonne of zinc produced, and the residue counts as hazardous waste because it carries heavy metals[2]. Handling and storing it is a recognised burden on the industry rather than a source of value[2].\n\nBeyond that, jarosite is of interest mainly to scientists and collectors — as a marker of acidic weathering on Earth, and as the Martian mineral that signalled past liquid water[2]."]
