The Earth's Vertical Files: Reading a 2.5-Billion-Year-Old Seabed Diary at the Book-Page Cliff

(Mount Song's Book-Page Cliff: The 'Primordial Stone Book' and Earth's 2.5-Billion-Year-Old Silent Archive)

This is not a cliff; it is a library of the abyss, a geological epic standing on its edge. Among Mount Song's many wonders, the Book-Page Cliff (Shūcè Yá) is perhaps the most visually stunning and philosophically profound. It is a sheer rock face where the Earth's crust has been thrust vertically, tilted, and eroded to reveal a monumental collection of stone slabs that look exactly like countless giant books stacked tightly on a shelf. This is not a metaphor; it is a literal open book of geological history, with each "page" representing millennia of sedimentation, pressure, and tectonic drama. To behold it is to stare directly into deep time.

Stand before it and read the story of the planet:
📖 The Granite Scripture: The "pages" are composed of quartzite, a metamorphic rock of incredible hardness and resilience. Formed from ancient sandstone that was buried, heated, and compressed in the Earth's mantle, it was then thrust vertically during the Songyang Orogeny (a mountain-building event). Erosion then exposed this massive, library-like wall.
⏳ The Chronicle of Time: This formation is part of the "Three Generations of Mount Song"—a sequence of rocks that documents three major geological eons. The Book-Page Cliff is a central chapter in this chronicle, its layers whispering secrets from 2.5 billion years ago.
🧭 The Cosmic Axis: Located near the summit of Junji Peak, the highest point of Mount Song, the cliff feels like a sacred archive at the center of the world. It physically embodies the mountain's title as the "Center of Heaven and Earth," serving as the geological proof for its cosmological claim.
