地质沉积地层剖面图

一张横向地质剖面图，约 1200 米沉积地层剖面，地质教科书图版风格。地表为褐色起伏线，带程式化树草符号。地层从上至下：淡黄灰砂质石灰岩（点状填充）、深灰页岩（细横排线）、红棕色泥岩（斜线填充）、实黑煤层（含 0.5m 刻度尺）、灰色砾岩（圆卵石符号）、底部深色基底花岗岩（交叉线+花岗岩斑点）。右三分之一处正断层斜贯，垂直位移约 80m；左三分之一处背斜褶皱。右侧深度刻度条 0–1200m（200m 间隔）。左下角图例。土黄、灰、深棕、黑、深红、石板色系，白色背景，细线高精度风格。

A wide landscape-format geological cross-section diagram showing roughly 1200 metres of sedimentary stratigraphy in the style of a field geology textbook plate. The surface topography at the top is a gently undulating brown line with sparse stylised tree and grass symbols. Below, horizontal to gently dipping rock strata are drawn with characteristic texture fills: the uppermost unit is a sandy limestone in pale buff with small dot pattern; beneath it, a dark grey shale layer with fine horizontal hatch marks; then a red-brown mudstone with diagonal dashes; then a coal seam in solid black with a thin 0.5 m scale tick; then a conglomerate in grey with circular pebble symbols; and at the base, a dark basement granite with cross-hatch plus granite speckle. A normal fault runs diagonally through the right third of the section, displacing layers by approximately 80 m, shown as a bold black line with dip-slip arrows. An anticline fold structure appears in the left third. Vertical depth scale bar on the right: 0 to 1200 m with 200 m intervals. A legend panel at bottom-left identifies each unit. Colour palette: earthy buff, grey, dark brown, black, crimson, slate. White background. Thin line weight with high precision.
