The first mention was used as “Bezier Pluton (Abez)” by Goutier et al. (2001, 2002). This unit was subsequently elevated to the suite rank in the preliminary report prepared by Bandyayera et al. (2013) to group plutons of similar composition. Subsequently, Goutier (2018) added the western end of the main pluton to sheet 33F08, while Goutier et al. (2021) described other similar plutons in sheet 33H12. One of the important features is the emplacement of this suite at the interface between the La Grande and Opinaca subprovinces. Intrusions previously defined as belonging to the Bezier Suite and present only in the Opinaca Subprovince were re-assigned to the Féron Suite. These changes relate to five intrusions on sheets 33G06 and 33G07.

The Bezier Suite defined by Goutier et al. (2001) consists of a K-feldspar porphyritic quartz monzodiorite and local quartz monzodiorite, monzodiorite and granodiorite. The various plutons in this suite are generally well visible on aeromagnetic maps because the delineation coincides with positive magnetic anomalies (Bandyayera et al., 2013). The exception is the pluton found in sheet 33G06. It occurs in an area of low magnetic susceptibility with a few small, poorly defined areas of higher susceptibility. Although its magnetic signature is weaker than other plutons in the Bezier Suite, it has the same lithological characteristics.

One of the determining factors is belongingness in the La Grande Subprovince. The main intrusion cut units in both the La Grande and Opinaca subprovinces. Units located in the La Grande Subprovince previously assigned to the Bezier Suite were re-assigned the Féron Suite.

The rock is greyish to whitish and its fresh surface is greenish to pinkish grey. Its grain size varies from medium to coarse and its structure is massive to slightly foliated. It is characterized by the presence of K-feldspar phenocrystals (6-12%) ranging in size from 0.5 to 3 cm. Feldspars are rectangular to square and zoned; they contain hornblende or biotite inclusions between growth rings. This growth zoning with mineral inclusions is one of the features of the Bezier Suite that distinguishes it from the Radisson Pluton. In addition to being in inclusion in feldspars, hornblende and biotite account for a large proportion of the rock (20-50%). Accessory minerals are magnetite, titanite and epidote. 

It is very common to observe centimetric fusiform enclaves of amphibolite and diorite (~3%). Bandyayera et al. (2013) also described the presence of 5% metric enclaves of fine-grained and foliated amphibolite and 3% centimetric angular fragments of mafic to intermediate composition.

Several plutons of a similar nature were identified in the northern region of sheets 33G05, 33G06 and 33G11 (Goutier et al., 2002), in sheets 33G02, 33G07 and 33G10 (Goutier, 2018), 33G09 (Bandyayera et al., 2013), and 33H12 and 33H13 (Goutier et al., 2021).
