This specimens is a classic example of \u003cb\u003eBrecciated Jasper\u003c\/b\u003e, or more technically, a \u003cb\u003esilicified volcanic breccia\u003c\/b\u003e.

The green clasts you are focusing on represent an older generation of volcanic rock that was shattered into angular fragments by tectonic or volcanic forces. These fragments were subsequently encased and cemented together by a secondary, silica-rich fluid. The vibrant red matrix that holds these green fragments together owes its colour to a high concentration of \u003cb\u003eHematite\u003c\/b\u003e (iron oxide) within the microcrystalline quartz (\u003cspan class=\"math-inline\" data-math=\"\\text{SiO}_2\"\u003e\u003cspan class=\"katex\"\u003e\u003cspan class=\"katex-html\" aria-hidden=\"true\"\u003e\u003cspan class=\"base\"\u003e\u003cspan class=\"strut\"\u003e\u003c\/span\u003e\u003cspan class=\"mord\"\u003e\u003cspan class=\"mord text\"\u003eSiO\u003c\/span\u003e\u003cspan class=\"msupsub\"\u003e\u003cspan class=\"vlist-t vlist-t2\"\u003e\u003cspan class=\"vlist-r\"\u003e\u003cspan class=\"vlist\"\u003e\u003cspan class=\"\"\u003e\u003cspan class=\"pstrut\"\u003e\u003c\/span\u003e\u003cspan class=\"sizing reset-size6 size3 mtight\"\u003e\u003cspan class=\"mord mtight\"\u003e2\u003c\/span\u003e\u003c\/span\u003e\u003c\/span\u003e\u003c\/span\u003e\u003cspan class=\"vlist-s\"\u003e\u003c\/span\u003e\u003c\/span\u003e\u003cspan class=\"vlist-r\"\u003e\u003cspan class=\"vlist\"\u003e\u003cspan class=\"\"\u003e\u003c\/span\u003e\u003c\/span\u003e\u003c\/span\u003e\u003c\/span\u003e\u003c\/span\u003e\u003c\/span\u003e\u003c\/span\u003e\u003c\/span\u003e\u003c\/span\u003e\u003c\/span\u003e) structure.\u003c\/p\u003e\n\u003cp data-path-to-node=\"6\"\u003eThe distinct olive and leek-green hues of the clasts are likely the result of \u003cb\u003eChlorite\u003c\/b\u003e or \u003cb\u003eEpidote\u003c\/b\u003e minerals present during the rock's initial formation. Because these fragments have been completely \"silicified\"—meaning their original mineral structure was replaced by silica—they possess the extreme hardness (6.5 to 7 on the Mohs scale) and the smooth, waxy luster characteristic of high-grade \u003cb\u003eJasper\u003c\/b\u003e.\u003c\/p\u003e\n\u003cp data-path-to-node=\"7\"\u003eThe sharp, vivid contrast between the green fragments and the deep red \"Xiaoshan Red\" matrix is the hallmark of material from the area of \u003cb\u003eMagu Village\u003c\/b\u003e. This striking aesthetic makes these specimens highly desirable for both geological study and lapidary work.
