Appinite complexes preserve evidence of mantle processes that produce voluminous granitoid batholiths. These plutonic complexes range from ultramafic to felsic in composition, deep to shallow emplacement, and from Neo-Archean to Recent in age. Appinites are a textural family characterized by idiomorphic hornblende in all lithologies, and spectacular textures including coarse-grained mafic pegmatites, fine-grained ‘salt-and-pepper’ gabbros, as well as planar and linear fabrics. Magmas are bimodal (mafic-felsic) in composition; ultramafic rocks are cumulates, intermediate rocks are hybrids. Their geochemistry is profoundly influenced by a mantle wedge extensively metasomatized by fluids/magmas produced by subduction. Melting of spinel peridotite sub-continental lithospheric mantle (SCLM) produces appinites whose geochemistry is indistinguishable from coeval low-K calc-alkalic arc magmatism. Coeval felsic rocks within appinite complexes and adjacent granitoid batholiths are crustal magmas. When subduction terminates, asthenospheric upwelling (e.g. in a slab window, or in the aftermath of slab failure) induces melting of metasomatized garnet SCLM to produce K-rich sho shonitic magmas enriched in large ionic lithophile and light relative to heavy rare earth elements, whose asthenospheric component can be identified by Sm-Nd isotopic signatures. Coeval late-stage Ba-Sr granitoid magmas have a ‘slab failure’ geochemistry, resemble TTG and adakitic suites, and are formed either by fractionation of an enriched (shoshonitic) mafic magma, or high pressure melting of a meta-basaltic protolith either at the base of the crust or along the upper portion of the subducted slab. Appinite complexes may be the crustal representation of mafic magma that underplated the crust for the duration of arc magmatism. They were preferentially emplaced along fault zones around the periphery of the granitoid batholiths (where their ascent is not blocked by overlying felsic magma), and as enclaves within granitoid batholiths. When subduction ceases, appinite complexes with a more pronounced asthenospheric component are preferentially emplaced along active faults that bound the periphery of the batholiths.

磷灰石复合物保留了产生大量花岗岩类岩床的地幔过程的证据。这些深部复合体的组成范围从超镁铁质到长质，从深部到浅部，从新亚奇时代到近代。食欲岩是一种质地家族，其特征是所有岩性均具有独特的角闪石，并且具有壮观的质地，包括粗粒黑镁质伟晶岩，细粒“盐和胡椒粉”辉长岩以及平面和线性织物。岩浆在成分上是双峰的（镁铁质的-长质的）。超镁铁质岩是堆积的，中间岩质是混合的。它们的地球化学受到俯冲产生的流体/岩浆广泛交代的地幔楔的深远影响。尖晶石橄榄岩亚大陆岩石圈地幔（SCLM）的熔融产生的磷灰石的地球化学与同期的低K钙碱性电弧岩浆作用没有区别。食源性复合物中的近代长英质岩石和邻近的花岗岩类岩基为地壳岩浆。当俯冲终止时，软流圈上升（例如，在板状窗口中，或在板状破坏之后）引起交代石榴石SCLM熔化，产生富含钾的sho shonic岩浆，相对于重稀土元素，其富含大型离子亲石性和轻度。可以通过Sm-Nd同位素特征识别出软流圈成分。中世纪晚期的Ba-Sr花岗岩类岩浆具有“平板破坏”的地球化学特征，类似于TTG和Adakitic套件，并且是通过富集（生铁质）镁铁质岩浆的分离而形成的，或在地壳底部或俯冲板块的上部高压熔融的玄武质原石。磷灰岩复合物可能是镁铁质岩浆的地壳表现形式，在弧形岩浆作用的持续时间内使地壳底陷。它们优先沿花岗岩基岩外围的断层带放置（在那里，它们的上升没有被上覆的长岩浆阻挡），并作为花岗岩基岩内部的飞地。当俯冲停止时，具有更明显的软流圈成分的Appinite配合物优先沿着束缚岩基岩外围的活动断层发生。磷灰岩复合物可能是镁铁质岩浆的地壳表现形式，在弧形岩浆作用的持续时间内使地壳底陷。它们优先沿花岗岩基岩外围的断层带安置（在那里，它们的上升没有被上覆的长岩浆阻滞），并且作为聚落在花岗岩基岩内部。当俯冲停止时，具有更明显的软流圈成分的Appinite配合物优先沿着束缚岩基岩外围的活动断层发生。磷灰岩复合物可能是镁铁质岩浆的地壳表现形式，在弧形岩浆作用的持续时间内使地壳底陷。它们优先沿花岗岩基岩外围的断层带放置（在那里，它们的上升没有被上覆的长岩浆阻挡），并作为花岗岩基岩内部的飞地。当俯冲停止时，具有更明显的软流圈成分的Appinite配合物优先沿着束缚岩基岩外围的活动断层发生。
