内华达山脉花岗岩地区的圆顶的共同特征是许多丘陵和其他具有圆顶形状的山峰。少数圆顶是对称的，底部大约是圆形或椭圆形的，但大多数是有点单边或不规则的。与这些穹顶形式相关联的是密切相关的结构。花岗岩被分成弧形的板或片，它们包裹在地形的形状上。去掉一个就会露出另一个，圆顶在表面上看起来就像洋葱一样，是由包裹层组成的。结构与形式的关系理论在解释这些特殊的形式和结构时，提出了两种普遍的理论。*根据一种理论，将花岗岩分成曲板是一种原始结构，可以追溯到该国的雕塑，并确定形式的特殊性。根据另一种理论，这种结构是随后产生的。。。
General Character of the Domes In the granite areas of the Sierra Nevada are many hills and other summits having the form of domes. A few of the domes are symmetric, with approximately circular or oval bases, but the majority are somewhat one-sided or irregular. Associated with these domelike forms are closely related structures. The granite is divided into curved plates or sheets which wrap around the topographic forms. The removal of one discloses another, and the domes seem at the surface to be composed, like an onion, of enwrapping layers. Theories of Relation Between Structure and Form In explanation of these peculiar forms and structures two general theories have been advanced.* According to one theory the separation of the granite into curved plates is an original structure, antedating the sculpture of the country and determining the peculiarities of form. According to the other theory the structure originated subsequently to . . .
