Microblade technology
open-in-new
<p>Microblade technology is a period of technological <a href="/facts/Microlith/K4svUap8">microlith</a> development marked by the creation and use of small stone blades, which are produced by chipping silica-rich stones like <a href="/facts/Chert/pmvbVy6U">chert</a>, <a href="/facts/Quartz/4n86tE2G">quartz</a>, or <a href="/facts/Obsidian/GW1DI93A">obsidian</a>. Blades are a specialized type of <a href="/facts/Lithic_flake/4RLPRpX2">lithic flake</a> that are at least twice as long as they are wide. An alternate method of defining blades focuses on production features, including parallel lateral edges and dorsal scars, a lack of cortex, a prepared platform with a broad angle, and a proximal bulb of percussion. Microblades are generally less than 50 mm long in their finished state. </p>
