Describe a rock to find its type. Here are some of the most popular ways students use Rock & Mineral Identifier every day:
Rocks and minerals form the Earth beneath your feet, yet many UK students struggle to tell granite from basalt, quartz from feldspar, or igneous from metamorphic rock. Applaa's Rock & Mineral Identifier transforms you into a geologist by asking you about colour, hardness, crystal form, and cleavage—the key diagnostic properties that experts use in the field. Rather than memorising lists, you describe what you observe and the tool narrows down the possibilities. It covers the KS3 rock cycle, GCSE Earth & Space rocks and minerals, and the mineralogy behind A-Level geology. Whether you're studying for your exam, working on a fieldwork project, or simply curious why some minerals sparkle while others don't, this tool guides you through the identification process step-by-step. See stunning photographs of each mineral and rock type, learn their formation history, and understand their real-world uses—from copper in electronics to feldspar in ceramics.
Observe your rock or mineral sample carefully and answer the tool's guided questions: What colour is it? Does it have crystals (and if so, what size)? What's the hardness (can a fingernail scratch it, can a coin scratch it, or do you need a knife)? Does it cleave along flat planes or fracture irregularly? Input these observations and the tool progressively narrows down the identity, showing photographs and properties of likely matches. Read the 'Formation & Uses' section to cement why this mineral matters—copper ores built the Bronze Age, feldspars fill ceramics factories, and quartz is the heart of electronics.
The worst error is relying solely on colour—many minerals share the same colour, so it's a starting point only. Students also confuse rocks (aggregates of multiple minerals) with minerals (single crystalline substances). Granite is a rock made of quartz, feldspar, and mica; you cannot have 'a piece of granite mineral' because granite is an aggregate. Hardness testing is often rushed; a mineral that's slightly scratched by a coin but easily scratched by a steel file is crucial diagnostic information that students miss by testing too quickly.
Getting started
Download Applaa free and explore the mineral gallery—see real photographs and properties of feldspar, quartz, mica, and other common UK rocks
Collect or gather samples from three different locations (garden, beach, or local park) and identify each using the tool's guided questions
Complete the 'Rock Cycle' challenge: starting from magma, trace how rocks transform through cooling (igneous), burial (metamorphic), and weathering (sedimentary)
Weekly exploration: identify one new sample each week; within a month, you'll recognise common UK rocks at a glance without the tool

A mineral is a single crystalline substance with a fixed chemical formula (e.g. quartz is always SiO₂). A rock is an aggregate of one or more minerals (e.g. granite is quartz + feldspar + mica). The tool helps you identify minerals first, then recognises the rock type based on which minerals make it up.
Purple colour suggests amethyst (a variety of quartz), but it's not certain—other minerals can be purple too. Test hardness (quartz scratches glass; 5.5 on Mohs), look for crystal shape (quartz is hexagonal), and check streak. The tool guides you through all three before confirming identity.
Both—it covers KS3 rock cycle, GCSE Earth & Space minerals, and A-Level mineralogy (crystal systems, optical properties, formation environments). You won't outgrow it; A-Level just adds detail to the foundations the tool establishes.
Feldspar is the most abundant mineral in Earth's crust and appears in most UK igneous rocks. It's used in ceramics, glass, and adhesives—understanding it is both exam-relevant and practically useful. The tool shows why granites (which contain lots of feldspar) are so common in Scotland and Wales.
