The palmierite supergroup, approved by the IMA-CNMNC, includes five mineral species characterised by the general crystal-chemical formula XIIM1XM22(IVTO4)2 (Z = 3). On the basis of the crystal-chemical arguments and heterovalent isomorphic substitution scheme M++T6+ ↔ M2++T5+, the palmierite supergroup can be formally divided into two groups: the palmierite group M12+M22+(T6+O4)2, and the tuite group M12+M222+(T5+O4)2. Currently, the palmierite group includes palmierite K2Pb(SO4)2, and kalistrontite K2Sr(SO4)2, whereas the tuite group combines tuite Ca3(PO4)2, mazorite Ba3(PO4)2, and gurimite Ba3(VO4)2. The isostructural supergroup members crystallise in space group R$\bar{3}$m (no. 166). The palmierite-type crystal structure is characterised by a sheet arrangement composed of layers formed by M1O12 and M2O10 polyhedra separated by TO4 tetrahedra perpendicular to the c axis. The abundance of distinct ions, which may be hosted at the M and T sites (M = K, Na, Ca, Sr, Ba, Sr, Pb, Rb, Zn, Tl, Cs, Bi, NH4 and REE; T = Si, P, V, As, S, Se, Mo, Cr and W) implies many possible combinations, resulting in potentially new mineral species. Minerals belonging to the palmierite supergroup are relatively rare and usually form under specific conditions, and their synthetic counterparts play a significant role in various industrial applications.

经 IMA-CNMNC 批准的棕榈石超群包括五种矿物，其特征为一般晶体化学式XII M 1 X M 2 2 ( IV T O 4 ) 2 ( Z = 3)。根据晶体化学论证和异价同构取代方案M + + T 6+ ↔ M 2+ + T 5+，棕榈石超群可以正式分为两组： 棕榈石群M 1 2+ M 2 2 + ( T 6+ O 4 ) 2，以及三组M 1 2+ M 2 2 2+ ( T 5+ O 4 ) 2。目前，棕榈石族包括棕榈石K 2 Pb(SO 4 ) 2和钾尖石K 2 Sr(SO 4 ) 2，而二钙石族则包括二钙石Ca 3 (PO 4 ) 2、菱沸石Ba 3 (PO 4 ) 2、和gurimite Ba 3 (VO 4 ) 2。同构超群成员在空间群R $\bar{3}$ m中结晶（编号 166）。棕榈石型晶体结构的特征在于，由由垂直于c轴的TO 4四面体隔开的M 1O 12和M 2O 10多面体形成的层构成的片状排列。不同离子的丰度，可能位于M和T位点（M = K、Na、Ca、Sr、Ba、Sr、Pb、Rb、Zn、Tl、Cs、Bi、NH 4和 REE；T = Si、P、V、As、S、Se、Mo、Cr 和 W）意味着许多可能的组合，从而产生潜在的新矿物种类。属于棕榈石超族的矿物相对稀有，通常在特定条件下形成，其合成对应物在各种工业应用中发挥着重要作用。
