      <p id="d2e2527">Subsequent to the approval of the nolanite supergroup report (see CNMNC newsletter 80) and during the review of the manuscript, some additional queries arose. Therefore a second round of voting has become necessary on a revised version in which the criticism raised has been addressed. The main update with respect to the previous approval is the following: the nolanite supergroup has been subdivided into three groups (kamiokite group, nolanite group, rinmanite group) not only in accordance with the largest charge of the species-defining octahedral cations (namely, cations at the <inline-formula><mml:math id="M140" display="inline"><mml:mi>M</mml:mi></mml:math></inline-formula>1 and <inline-formula><mml:math id="M141" display="inline"><mml:mi>M</mml:mi></mml:math></inline-formula>2 sites, which are considered as a whole) but also taking into account the dominant <inline-formula><mml:math id="M142" display="inline"><mml:mi>X</mml:mi></mml:math></inline-formula> species (<inline-formula><mml:math id="M143" display="inline"><mml:mrow><mml:mi>X</mml:mi><mml:mo>=</mml:mo></mml:mrow></mml:math></inline-formula> O or OH).</p>

      <p id="d2e2578">Concurrent with the approval of the new mineral svornostite-(NH<sub>4</sub>) (IMA no. 2024-068; this newsletter), the svornostite group has been established. As part of this, the minerals svornostite and oldsite have been renamed svornostite-(K) and oldsite-(K), respectively. The svornostite group is divided into the svornostite subgroup, which includes svornostite-(K), svornostite-(NH<sub>4</sub>), and oldsite-(K), and the rietveldite subgroup, which includes rietveldite and zincorietveldite.</p>

  <title>Voting majority for CNMNC proposals on new minerals, nomenclature changes, and mineral groups</title>
      <p id="d2e2614">(Ferdinando Bosi, Frédéric Hatert, Marco Pasero, and Stuart J. Mills)</p>
      <p id="d2e2617">The officers' proposal, stemming from discussions among members during the CNMNC business meeting on 20 August 2024, at the European Mineralogical Conference (EMC) in Dublin, to increase the voting majority required for proposals submitted to the CNMNC has been approved. As a result, the CNMNC has adopted a new threshold requiring more than 75 % positive votes for the approval of new minerals, nomenclature changes, and the establishment of mineral groups or supergroups. The chair or the officer in charge retains the authority to suspend voting if significant concerns are raised by members.</p>
