Orthoclase - an overview | ScienceDirect Topics

Orthoclase feldspar may arise from regional metamorphic processes, and is a common ingredient in various crystalline schists (Table 6.1). Orthoclase changes to kaolinite (Section 5.2.1.2) and sericite with the process of kaolinization and sericitization, respectively.

Feldspar | Minerals Education Coalition

Feldspar can be replaced by other minerals and mineral mixtures of similar physical properties. Minerals that could be used to replace feldspar include pyrophyllite, clays, talc, and feldspar-silica (quartz) mixtures. The abundance of feldspar will make these substitutions unnecessary for the foreseeable future.
