34 Peresani et al. Gli inse<strong>di</strong>amenti epigravettiani al Palughetto<br />

Fig. 13 - Palughetto MN. Nuclei a lamelle e relativi schemi <strong>di</strong>acritici: 1 - Schema operativo 1: nucleo su scaglia. Si riconosce un’unica fase <strong>di</strong><br />

sfruttamento lungo lo spigolo del supporto. 2 - Schema operativo 2a: nucleo su placchetta sfruttato me<strong>di</strong>ante 3 sup. successive <strong>di</strong> scheggiatura.<br />

La prima (A) si imposta sulla faccia larga del supporto per l’estrazione <strong>di</strong> alcune lamelle in sequenza; la seconda (B) vede l’estrazione <strong>di</strong> un<br />

lamella lungo lo spigolo <strong>di</strong>stale della placchetta, che viene poi sfruttata come piano <strong>di</strong> percussione funzionale alla terza sup. (C) impostata<br />

lungo lo spigolo laterale del supporto. 3 - Schema operativo 2b: nucleo su scheggia articolato su 2 sup. <strong>di</strong> scheggiatura successive ed un unico<br />

piano <strong>di</strong> percussione; le due sup. opposte (A e B) sfruttano la naturale convessità degli spigoli laterali (foto e schema <strong>di</strong>acritico R. Duches).<br />

Fig. 13 - Palughetto MN. Bladelet cores and their <strong>di</strong>acritical schemes: 1 - Operative scheme 1: core on shatter. A single phase of exploitation<br />

is recorded on the ridge of the blank. 2 - Operative scheme 2a: core on slab exploited through 3 successive flaking surfaces. The<br />

first (A) lied on the large side of the blank for extracting few bladelets in sequence; the second (B) involves the extraction of a bladelet<br />

along the <strong>di</strong>stal ridge of the slab which then is used as a striking platform to support the third surface (C) on the side ridge of the cobble.<br />

3 - Operative scheme 2b: core on flake structured with 2 successive flaking surfaces and one single striking platform; the two opposed<br />

surfaces (A and B) use the natural convexity of the sides (photo and <strong>di</strong>acritic scheme R. Duches).
