For eleven of these, initial Fe₃O₄<span>&nbsp;</span>content is low (generally &lt;1%) and the<i>J_s-T</i><span>&nbsp;</span>curves are irreversible. The heating curves show variable greater (up to 10 times) than it is initially. This behavior is attributed to the production of magnetite from a thermally unstable phase — apparently FeS. Four of the remaining seven C2 chondrites contain Fe₃O₄<span>&nbsp;</span>as the only significant magnetic phase: initial magnetite contents range from 4 to 13%. The remaining three C2 chondrites contain iron or nickel-iron in addition to Fe₃O₄. These seven C2 chondrites show little evidence of the breakdown of a thermally unstable phase.</p></div></div></div><ul id="issue-navigation" class="issue-navigation u-margin-s-bottom u-bg-grey1"></ul> application/pdf 10.1016/0012-821X(75)90167-3 en Elsevier Thermomagnetic analysis of meteorites, 2.
